The Arizona Cardinals have elevated defensive tackle Keilen Dykes from the practice squad to the 53-man active roster

The Cardinals also released wide receiver Lance Long and re-signed wide receiver Onrea Jones to the practice squad. Long joined the Kansas City Chiefs practice squad Wednesday.

The 6-foot-3, 305-pound Dykes, who played at West Virginia, spent 2008 on the Cardinals practice squad after signing with the team as an undrafted free agent.

Dykes had a good chance of making the squad a week ago had he not missed most of training camp with a quadriceps injury.

Coach Ken Whisenhunt said he made the move because of the possibility the team will be without Kenny Iwebema for Sunday's game at Jacksonville. Iwebema sprained his right ankle in Arizona's season-opening 20-16 loss to San Francisco.

"Going against a team that runs the ball very well like Jacksonville does, I'm scared to go in this game with only five down linemen," Whisenhunt said.

The coach indicated the Cardinals would have liked to re-sign Long to the practice squad had the Chiefs not picked him up. Instead, Arizona re-signed Jones.

Jones was cut by the Cardinals at the end of preseason and was briefly on the Washington Redskins practice squad before being released on Tuesday.
