Broncos activate LB Miller

The Denver Broncos activated linebacker Von Miller, the team announced Saturday.

To make room for Miller on the 53-man roster, Denver waived wide receiver Tavarres King.

Miller, 24, returned to practice this week after serving a six-game suspension for violating the NFL's substance-abuse policy.

Coach John Fox said Friday he expects Miller to make an immediate impact Sunday night when the Broncos take on the host Indianapolis Colts.

"I think it's probably fair to say he's going to start," Fox said. "We're probably not going to announce the starting lineup but I wager he's going to start."

The 2011 NFL defensive rookie of the year has 30 sacks in his first two seasons, including a franchise-record 18 1/2 last season.

King, a fifth-round draft pick this year out of Georgia, spent six weeks on Denver's practice squad and one week on the club's active roster. He caught five passes for 64 yards during the preseason.
