The Dallas Cowboys were not too concerned when they sent Morris Claiborne for an MRI on his left knee and it turns out it’s just a minor sprain for the first-round draft pick. Claiborne is expected to miss about a week, according to Todd Archer of ESPN Dallas, with an MCL sprain. The cornerback underwent the MRI on Friday and has not practiced since Wednesday. It’s good news for the Cowboys, who are counting on big things from Claiborne. “A little bit disappointing,†he said, “but it's not too much because I know it's not something serious. I know it's something I can come back from. You can't just get mad over something you can't control.†Source: National Football Post
