The Indianapolis Colts (6-5) are preparing to host the Tennessee Titans (6-5) on Sunday at Lucas Oil Stadium in what is expected to be a physical AFC South matchup.

Both teams are looking to find a way into the playoffs, which means this matchup will have plenty of implications down the stretch—not only in the divisional race but the AFC playoff race as well.

Here are five Colts to watch during the Week 13 matchup at Lucas Oil Stadium:

QB Jacoby Brissett

A player that everyone will be watching on Sunday is Brissett. After the Colts have gone four consecutive games without throwing for over 200 yards as a team, Brissett’s status as the future of the Colts’ quarterback room has come into question.

Brissett certainly has the tools to be a successful quarterback in the NFL. He’s intelligent, he has strong pocket mobility and he has a rocket for an arm. But he hasn’t been trusting it for the majority of the season. Those concerns reared their ugly head in the Week 12 loss against the Texans.

The Titans are likely to sell out against the run, which means Brissett will have his chances to air it out. Whether he will take advantage of those chances is what likely determines the game.
