McClain has an injured groin, believed to have been sustained in the second half of Dallas's game against the Tennessee Titans last week. He played the entire game against the Titans but has not practiced this week.
“You’ll miss him,” Cowboys owner Jerry Jones said Friday morning on 105.3 The Fan [KRLD-FM]. “I think you could expect him probably not to play, but he won’t tell you that. We’re not for sure when he had this injury. He might have had it early in the game. You listen to him, he wants to play and thinks he might play. But we have him as doubtful, of course.”
The former top-10 pick has retired twice and been arrested three times since entering the NFL in 2010. McClain didn't play last season but impressed the Cowboys enough in training camp to earn a starting spot in the absence of injured middle linebacker Sean Lee.
McClain, who the Cowboys acquired in a trade from the Baltimore Ravens for a future seventh-round draft pick, has started both of Dallas's games this season, recording 15 tackles, a sack and an interception.
Justin Durant would likely start at middle linebacker in McClain's place.
