INDIANAPOLIS -- Colts quarterback Andrew Luck and safety Clayton Geathers suffered concussions in Sundays 24-17 win over the Tennessee Titans.The statuses of both players against the Pittsburgh Steelers on Thanksgiving are in doubt because of the short turnaround in between games and because they must complete the NFLs concussion protocol before being cleared.Well after we were all done with the locker room, both guys didnt feel right and went in the training room, and both were evaluated for concussions. Both are in the protocol, said Colts coach Chuck Pagano.Luck was sacked twice and hit eight other times against the Titans. He is believed to have suffered the concussion when Titans defensive tackle?Austin Johnson landed on top of him after recording a sack with 11:46 remaining in the game.If Luck is not cleared,?Scott Tolzien will start in his place against the Steelers. Tolzien is 56-of-91 for 721 yards with a touchdown and five interceptions in six career appearances. He has attempted only one pass since the 2013 season.He has a limited amount of exposure, but he is a pro, Pagano said of Tolzien. Again, if he has to roll and be the guy, then he will do a great job. He prepares really well every single day.After Thursdays game, the Colts dont play again until Dec. 5 against the New York Jets.The Colts (5-5), who are on a two-game winning streak, are trying to catch the Houston Texans (6-3) in the AFC South.

Find out below and then cast your vote... Marcus BucklandThe winner is ... Stan Wawrinka Naturally the focus is on the year-end No 1 position with Andy Murray and Novak Djokovic perhaps on a collision course to decide everything in a dream final.As much as I would love to see that I have a sneaking feeling, based on nothing but gut instinct, that Stan Wawrinka is going to provide a twist and add another notable, and unexpected title to his burgeoning CV.When hes hot hes boiling and the reigning US Open champion has shown in the past that he can play lights out tennis at the 02. His recent semi-final against Roger Federer (albeit a match he lost) was arguably the best in the history of the event since it moved to London. Very quiet recently Stan has what it takes to be the man again. Tour Finals: Panel predictions ATP World Tour Finals 2016: The Sky Sports panel offer their predictions Peter FlemingThe winner is... Andy Murray (Just) You have to say Andy Murray is the favourite. Hes the guy who has played so well over the past six months really and the way Novak Djokovic has played over the same period really, hes not nearly as confident and not mentally where he wants to be.But, he could get it back quickly because his record is so good over the last four years. His record is 18-1 over that time, or something. Andys record is only 4-7, it means if Novak can regroup quickly, he can be a real match.If we can get those two guys in the final next Sunday, then what an epic that will be. Ive give Murray a 51-49 shot over Novak.Leif ShirasThe winner is ... Andy Murray Difficult selection with the talent here.dddddddddddd Im happy to go with Andy Murray. I feel like hes in that special place where hes never been before.The confidence level is high. Ivan Lendl is here this week to make sure theres no let up and thats hes continuing to play the tennis he is playing and continue to do the things he needs to do which is be aggressive with the forehand, continue to serve well.Obviously hes in great physical condition so Im going to go with Andy. A look back at Andy Murrays year, which has seen him enter the World Tour Finals as world No 1 Barry MillnsThe winner is ... Andy Murray Despite being drawn in the tougher group I think Andy Murray will go on and win the title.Hes in the form of his life, the incentive to hang onto his new world No 1 ranking will be immense, the crowd support for him should be greater than ever before (with Federer and Nadal both absent) and if the surface is quicker this year (as the build-up has suggested) then I believe that can work well for him as it did in Asia, as well as back in the summer at Queens and Wimbledon.
