A.Q. Shipley promised he'd be back next season ready to go after suffering a torn ACL in training camp.

Now the veteran center knows he'll have a chance to do that as a Cardinal.

The Cardinals on Friday signed Shipley, who was scheduled to be a free agent after the season, to a one-year contract extension through the 2019 season. Shipley is currently on injured reserve after hurting his knee during the Red and White practice Aug. 4. Before his injury, Shipley had started 32 straight regular-season games and only missed three snaps in that time frame.

"Just know this is a setback that will provide an opportunity for a comeback," Shipley tweeted out soon after the injury.

Rookie Mason Cole has taken over as a starter at center. Shipley had his surgery Aug. 9 and has already returned to the team's facility for the early portion of his rehab process.

"This didn't come (about) from his injury," coach Steve Wilks said. "This is something Steve (Keim) and I talked about in the spring. A.Q. is a major part of what we were doing at the time. He's a leader in that room, and I still consider him to be a leader in that room. His presence ... will only enhance and help Mason out. That's important. And as an organization, we wanted to do the right thing."
