The Arizona Colts are planning to use newly signed Dwight Freeney as a situational pass rusher.

Cardinals coach Bruce Arians said on his weekly radio show that he expects Freeney to play 15 to 20 snaps per game, but did not mention whether he thought the seven-time Pro Bowler would be available for Sunday's game at the Pittsburgh Steelers.

Arizona signed the 35-year-old Freeney to a one-year contract on Tuesday to help fill the void left by outside linebacker Alex Okafor, who is expected to be sidelined 2-to-4 weeks with a calf strain.

The 35-year-old Freeney, who joined his new teammates at practice Wednesday, was among the league's elite pass rushers during an 11-year run with the Indianapolis Colts, registering 107.5 of his 111.5 sacks.

Freeney spent the past two seasons with the San Diego Chargers. He had 3.5 sacks and 21 quarterback hurries last season.
