New Cardinals linebacker Quentin Groves (52) tackles running back Beanie Wells during a game in 2010 when Groves played for the Raiders.

The Cardinals signed a veteran linebacker Thursday, but it wasn't Clark Haggans.

Instead, the Cards turned to Quentin Groves, a four-year pro who was once a second-round draft pick of Jacksonville and was traded to Oakland in 2010.

Groves, 6-foot-3 and 265 pounds, has 95 tackles in his career with 2½ sacks, two interceptions, six passes defensed, three forced fumbles and two fumble recoveries. His sack total came entirely as a rookie in Jacksonville.

To make room on the roster, the Cards cut wide receiver Marc Wilson, an undrafted rookie out of tiny St. Anslem.

There has been speculation the Cards will bring back Haggans, who has been with the Cards since 2008. Regardless, the team probably needed to add depth at outside linebacker, where much is unproven. Sam Acho and O'Brien Schofield are the projected starters, but beyond that are untested veterans Brandon Williams and Antonio Coleman, along with undrafted rookies Zach Nash and Broderick Binns.

Stewart Bradley can and has played a little bit on the outside, but Bradley is expected to work mostly as an inside presence in the Cards' 3-4 alignment.

Groves did work out for the Giants earlier this offseason.

The Cardinals have already topped out on their 90-man limit for the offseason, so any roster addition must be accompanied by a corresponding release of a player.

The Cards completed their first week of organized team activities Thursday. They resume on-field work Tuesday.
