Englewood, CO ( - The Denver Broncos officially ended Von Miller's season Tuesday, placing the star linebacker on injured reserve.

Miller suffered a torn anterior cruciate ligament in his right knee last Sunday, delivering a blow to a team with Super Bowl aspirations that just wrapped up a first-round bye.

Miller was hurt on a non-impact play in the first quarter, and an MRI on Monday revealed the torn ACL, Broncos coach John Fox said.

Fox said recovery time for the injury is usually between six and nine months and that Miller "should be ready for camp next season."

Miller served a six-game suspension at the start of the season for violating the NFL's substance-abuse policy and the Broncos won all six games. He played just eight games this season, compiling 34 tackles and five sacks.

Filling his spot on the roster is linebacker Brandon Marshall, who was elevated from the practice squad. Marshall, a fifth-round pick in the 2012 draft, played five games for the Jaguars last season.

In other news, wide receiver Nathan Palmer was signed to Denver's practice squad.
