Indianapolis Colts quarterback Jacoby Brissett left Sunday’s game against the Steelers in Pittsburgh in the second quarter with a left knee injury.
He was initially listed as questionable to return.
On an incomplete pass play, Pittsburgh’s Cam Hayward knocked one of Brissett’s teammates into him. He eventually jogged off the field and was replaced by Brian Hoyer, who completed the drive with a touchdown pass for a 10-3 Colts lead.
Brissett completed 4 of 5 passes for 59 yards before exiting.
Brissett was elevated to starter shortly before the start of the season when Andrew Luck unexpectedly retired.
