It turns out that he won't be available for tomorrow's game.
When Brissett exited the game against Pittsburgh last Sunday, it didn't look good. While Brissett has been a limited participant in practice this week, the team has also been giving quarterback Brian Hoyer - who had three touchdown passes in relief work last week - extra practice reps just in case.
However, the Colts have made a change to Brissett's status for this weekend. It's pretty apparent that he could handle the starting role if necessary.
Indianapolis Colts head coach Frank Reich ruled out just two players ahead of the Week 10 matchup against the Miami Dolphins-wide receivers T.Y. Hilton and Parris Campbell.
It'll be interesting to see how Hoyer performs in his first start since 2017.
The Colts (5-3) trail the Texans (6-3) by half a game in the standings and have three straight AFC South games following Sunday's meeting with the one-win Dolphins.
The Colts also announced that cornerback Pierre Desir has been downgraded to doubtful.
But Saturday, the Colts announced Brissett wouldn't play and promoted third-string quarterback Chad Kelly from the practice squad to the active roster.
Since taking over as the Colts starter upon Andrew Luck's stunning retirement, Brissett has been terrific.
