Calais Campbell may be able to give the Arizona Cardinals a boost in a matchup between two NFC contenders Sunday.
Cardinals head coach Bruce Arians said on a conference call that his defensive end is "50-50" to play against the 5-1 Philadelphia Eagles this weekend.
The Cardinals lead the NFC West at 5-1 and could create further separation from the San Francisco 49ers and Seattle Seahawks with another win.
Campbell has been fighting off an MCL injury suffered against the Denver Broncos in Week 5. Tight end Julius Thomas hit Campbell low on a play that Arians called the dirtiest he'd ever seen.
