Dallas Cowboys defensive end DeMarcus Ware has admitted that he was "surprised" to see teammate Sean Lee miss practice and be ruled out for their week 15 clash.

Lee sustained a neck injury during his side's defeat to the Chicago Bears on Monday and was forced to leave the game and now will reportedly miss the Cowboys' game with the Green Bay Packers on Sunday.

"I was surprised," Ware told ESPN. "I just saw him in the meeting and I was like 'Hey what's wrong? You alright?' He was a little bit upset but things happen and you gotta keep rolling."

Dallas are 7-6 in their season ahead of their week 15 clash.
