Colts quarterback Jacoby Brissett sprained the medial collateral ligament in his left knee in Sunday's game against the Steelers, coach Frank Reich announced on Monday.
Reich told reporters he's "optimistic" that Brissett can play on Sunday against the Dolphins.
Brissett 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. Brissett visited the medical tent twice and was seen trying to stretch his leg before being sidelined for the rest of the game. Backup Brian Hoyer entered the contest in his absence.
After the 26–24 loss, coach Frank Reich told reporters he thought Brissett's injury was "MCL-ish" and said, "It looks like a sprain. We'll see to what degree."
Brissett took over as Indianapolis's starter after Andrew Luck surprisingly announced his retirement in August. Through eight games this season, Brissett has tallied 1,649 yards with 14 touchdowns and a 64.8 completion percentage. The Colts are 5–3 and sit in second place in the AFC South.
