Colts quarterback Jacoby Brissett has been ruled out for Sunday's game against the Dolphins, the team announced on Saturday.
Brissett injured his left knee in last Sunday's game against the Steelers. He exited the game in the second quarter after being hit by his own lineman, Quenton Nelson. The signal-caller dropped to the ground after Nelson was pushed back into his left knee and eventually walked off the field under his own power.
An MRI on Monday confirmed Brissett suffered a sprained MCL, and he was originally listed as questionable for the upcoming game.
