The Indianapolis Colts elevated quarterback Chad Kelly to the 53-man roster on Saturday as starter Jacoby Brissett was downgraded to out for Sunday's game against the Miami Dolphins.

Brian Hoyer is expected to start in Brissett's place, with Kelly serving as backup. The Colts (5-3) gave Hoyer extra reps in anticipation of a possible start against the Dolphins (1-7).

Kelly completed 54 of 73 passes for 583 yards with two touchdowns and two interceptions in four preseason games with the Colts this summer, then was signed to the practice squad on Sept. 19.

Wide receiver Marcus Johnson was also elevated from the practice squad, while wideout Deon Cain and defensive tackle Kyle Peko were waived.

Brissett (knee) had been listed as questionable and was limited in practice this week.

After returning to practice on Wednesday, Brissett participated in a limited role throughout the week after sustaining a sprained MCL early in the second quarter last Sunday in a 26-24 road loss to the Pittsburgh Steelers. Guard Quenton Nelson was knocked back into Brissett and rolled up the quarterback's leg.

An MRI exam on Monday revealed a sprained MCL but no significant structural damage.

Brissett, the full-time starter in the wake of Andrew Luck's preseason retirement, has thrown for 1,649 yards with 14 touchdowns and three interceptions, good for a 99.7 passer rating.

The Colts also downgraded cornerback Pierre Desir to doubtful. He's missed the past two games with a nagging hamstring injury.
