The Arizona Cardinals will look to Quentin Groves to fill the void at linebacker with O'Brien Schofield lost for the rest of the season.

Schofield was placed on injured reserve on Tuesday after tearing ankle ligaments in the Cardinals' loss to the Green Bay Packers this past week. The injury now gives Groves, whom coach Ken Whisenhunt says has played well, an opportunity to start in Schofield's place after primarily being a backup and giving spot reliefs at linebacker.

"It's unfortunate circumstance that my brother O'Brien had to go down, but we have to keep the ball rolling," said Groves, who has started for both Oakland and Jacksonville at times previously in his career. "Next man up. That's what this league is about.

Groves, a five-year veteran, has 17 tackles and two sacks in the Cardinals' nine games. The Auburn product began his career playing two years with the Jacksonville Jaguars before spending time with the Oakland Raiders from 2010-2011.

The Cardinals defense, while mediocre against the run, has been impressive against the pass, ranking third in the league with only 194.6 passing yards allowed per game.

Arizona will return to action against the Atlanta Falcons on the road on Nov. 18.
