Cincinnati Bengals running back Cedric Peerman is likely done for the season after fracturing his left forearm in a preseason game against the Jaguars on Sunday night.
He was fitted with an air cast on the sideline after being injured during a play in the first half.
Peerman, a special teams captain, has led the team in special teams tackles for two straight seasons.
He earned his first Pro Bowl berth last season.
Peerman's injury wasn't the only one suffered by the Bengals during the game. Wideout A.J. Green limped off the field with a right knee injury in the first quarter and didn't return.
Cornerback Adam Jones was also scratched after straining a calf while backpedaling in pregame warmups.
