The Denver Broncos have placed safety Quinton Carter on injured reserve with a knee injury, according to the team's Twitter account. In a corresponding move, the Broncos promoted safety Duke Ihenacho to the active roster.
Carter, who has been hobbled all season by his troublesome knee, could opt to have microfracture surgery, per Mike Klis of the Denver Post. Carter's knee started bothering him during the offseason, but declined to have a procedure of any sort done as he continued to practice and play through pain. The injury has limited him in practice for the past few weeks, but the breaking point apparently came in last week's game against the Houston Texans.
Rahim Moore, who played well last weekend against the Texans, could be in line to take the majority of Carter's reps.
The Broncos also promoted linebacker Mike Mohamed to the active roster on Saturday. He'll take the spot of Joe Mays, who has been suspended for Sunday's game against the Oakland Raiders.
