TEMPE, Ariz. -- Arizona outside linebacker Will Davis broke his left leg against the Kansas City Chiefs and is expected to be out for the season.
Davis started the game in place of Clark Haggans, who has missed three of the last four games with a groin injury.
Whisenhunt said he expects Haggans back this week and, with rookie O'Brien Schofield now the backup, does not anticipate adding another player at that position.
Davis, a sixth-round draft pick out of Illinois in 2009, had started the three games that Haggans was injured.
