ARLINGTON, Texas -- Dallas Cowboys middle linebacker Rolando McClain didn't finish Sunday's game against the Houston Texans after re-injuring his groin. McClain finished with six tackles and one quarterback hurry in the 20-17 overtime victory.

McClain missed Week 3 at St. Louis with the same injury. The Cowboys' medical staff said he would miss up to four weeks with the injury, but he returned after sitting out just one game.

"The doctor said two-to-four weeks and obviously it hasn’t been that long," McClain said. "Coming back and playing after one week, you will have your ups and downs. It's all part of the game. You need to be out there and we need everybody out there."

McClain has become a solid force in the middle of the Cowboys' defense this season. Rookie Anthony Hitchens would see increased playing time if McClain is out.

"We still need to be able to lineup regardless of who's out there," coach Jason Garrett said. "And we didn't line up the right way and it hurt us."
