INDIANAPOLIS -- The Indianapolis Colts second straight win may have cost them quarterback Andrew Luck.Luck entered the concussion protocol after complaining about concussion-like symptoms following Sundays 24-17 victory over Tennessee. Coach Chuck Pagano said Monday he believes the injury concussion occurred in the fourth quarter, but couldnt cite which play Luck was injured on.The surprising news came a little more than 24 hours after Pagano told reporters the Colts had no significant injuries from the game. Indy (5-5) hosts Pittsburgh on Thanksgiving night, leaving little time for Luck to recover. If he cant play the Colts will likely go with backup Scott Tolzien, who hasnt thrown a regular-season pass since the 2013 season.Andrew and (safety) Clayton Geathers, pretty much well after we were all done with media and the locker room and things like that, both guys didnt feel right, Pagano said Monday. Both guys went in the training room and saw our docs and both were evaluated for concussions. Both are in the protocol and its up to the docs and trainers to monitor that situation, so thats where thats at.Geathers also entered the protocol after apparently getting hurt on the final defensive play of the game.Even with Luck healthy and playing pretty well this year, its been a struggle. Indy needed fourth-quarter rallies to win its first two games and had to hold off opponents comeback bids in each of the last three wins.Last year, Luck missed nine games with multiple injuries, the last seven because of a lacerated kidney. To help keep him healthy this season, the Colts reduced his workload at practice. But he has been sacked a league-high 35 times.So when Luck was not taking snaps at practice Monday, it wasnt immediately clear whether it was part of the routine or a new injury.After practice, Pagano clarified what had happened -- and the process Luck must undergo before playing again.You have to feel better, you have to take an impact test and pass an impact test, then practice non-contact, then have another day and then take another impact test and be cleared by an independent, he said. Again, that is our trainers and docs that will handle that.The timing couldnt be worse.Indy just moved back into second place in the AFC South and got back into the playoff hunt by stringing together its first winning streak of the season. A third straight win would be a major step forward for a team that has been inconsistent all season.Now, the Colts will probably face an old nemesis, Pittsburgh (5-5), without their star quarterback.The Steelers have won three straight in the series and 13 of the last 15 since 1984, and they just snapped a four-game losing streak with a win Sunday at Cleveland.Its not the first time the Colts have faced this sort of predicament. Lucks 2015 injuries forced the Colts to rely on four additional quarterbacks to get through a season in which they finished 8-8 and missed the playoffs for the first time since 2011. And Indy won the final game after signing Josh Freeman and Ryan Lindley as replacement quarterbacks the week of the game.Tolzien has two career starts, both in 2013 when he replaced injured Green Bay quarterback Aaron Rodgers. He finished that season 55 of 90 with 717 yards, one touchdown and five interceptions.But the short week doesnt leave much time for Pagano to fret.He has a limited amount of exposure, but he is a pro, Pagano said. Again, if he has to roll and be the guy then he will do a great job. He prepares really well every single day.---For more NFL coverage: http://www.pro32.ap.org and http://www.twitter.com/AP-NFLCubs Jerseys 2019 . -- In one brief spurt, Brazil turned a close game into a rout and proved again it will be a strong World Cup favourite.

Here are five things to know as you prepare to immerse yourself in football.BEST GAMENo. 1 Alabama vs. No. 20 USC? No. 10 Notre Dame at Texas? No. 18 Georgia vs. No. 22 North Carolina. No. 5 LSU vs. Wisconsin at Lambeau Field. And thats just to name a few. Lots of interesting matchups from which to choose, but the best looks as if it will be the last.No. 11 Mississippi faces No. 4 Florida State in Orlando, Florida, on Monday night. The Rebels are in a bit of a reload season after losing three first-round draft picks that were the heart of a team coming off two straight New Years Six bowl appearances. There is still plenty for the Ole Miss fans to be excited about, starting with Chad Kelly, one of the best quarterbacks in the country, throwing to a bunch of speedy receivers.Florida State seems set everywhere but quarterback. Redshirt Deondre Francois takes over a team with national title hopes. Dalvin Cook is one of the best running backs in the country and safety Derwin James is a versatile playmaker on defense.Add in some SEC-ACC bragging rights and you have the game of the week.HEISMAN WATCHNo player could do more for his Heisman Trophy hopes in Week 1 than Houston quarterback Greg Ward Jr. The 15th-ranked Cougars open against No. 3 Oklahoma at NRG Stadium, the home of the Houston Texans. If Ward, who passed for 2,828 yards, ran for 1,108 yards and accounted for 38 touchdowns last season, has a big game and leads the Cougars to an upset, he can vault himself into the heart of a crowded field of Heisman contenders that includes three of the top four vote-getters from last season.If Ward and the Cougars play a clunker, you can probably scratch him off the list of possible winners.NUMBERS TO KNOW-Longest current season-opener winning streaks:Florida -- 26. The Gators play UMass at the Swamp.USC -- 17. The Trojans face Alabama in Arlington, Texas.Ohio State -- 16. The Buckeyes host Bowling Green.-Nebraska coach Mike Riley and Virginia coach Bronco Mendenhall each enter the season with 99 victories. The Cornhuskers open the season at home against Fresno State. Mendenhalls first game as Cavalierrs coach is home against FCS power Richmond.dddddddddddd(SLIGHTLY) OFF THE RADARBYU opens against Arizona at University of Phoenix Stadium in Glendale, Arizona, marking the return of Cougars QB Taysom Hill for a sixth season of eligibility.Hill lost most of each of the last two seasons to injuries. He also did a Mormon mission at the start of his career. So now at 26, a quarterback who was in the same recruiting class in 2009 as Matt Barkley, gets one more chance to lead the Cougars. When healthy Hill drew comparisons to Tim Tebow. He won a tight competition with Tanner Mangum to win the starting job.The Arizona game is the first in a string of high-level opponents for the independent BYU. Also on the schedule: Utah, UCLA, West Virginia, Toledo, Michigan State, Mississippi State, Boise State and Cincinnati. All of those teams played in bowl games last season. All but Cincinnati spent at least one week ranked.Regardless of how well the Cougars do, a full season from Hill will be a victory.COACH IN NEED OF A WINIts never too early to start the hot seat watch.Texas A&Ms Kevin Sumlin and Auburns Gus Malzahn enter the season with pressure to change the trajectory of their programs. Both start with huge home openers. The Aggies take on No. 16 UCLA and Auburn host No. 2 Clemson and Deshaun Watson.Big challenges and great opportunities to show things are headed in the right direction. Also, a chance to start 0-1 in front of the home crowd.For Auburn, a solid showing against a team that pushed Alabama in the championship game could make a loss in the opener palatable to Malzahns critics. Thats not necessarily the case for Sumlin. UCLA has the ranking and the star quarterback in Josh Rosen, but the Aggies are favored at home by a couple points. It is a winnable game. The Aggies are 1-6 at Kyle Field against ranked teams under Sumlin. Fall to 1-7, with an always tough slate of SEC West games still ahead, and things almost immediately get uncomfortable in College Station, Texas.---Follow Ralph D.
