Ernie Sims set for MRI

ARLINGTON, Texas -- Dallas Cowboys linebacker Ernie Sims will undergo an MRI on his hip/groin on Monday after he was forced from Sunday's 37-36 loss to the Green Bay Packers on the final play of the first half.

Sims, who started at weak-side linebacker and moved to middle linebacker after Justin Durant aggravated a hamstring injury, was hurt as part of a group that tackled running back Eddie Lacy.

"When I tackled Lacy I kind of opened up and as I went to the ground everybody landed on me," Sims said. "I tried to come back but that thing’s painful. I can’t explain the pain I feel."

Sims said X-rays were negative.

With Sims and Durant out of the game (and Sean Lee and Bruce Carter inactive because of neck and hamstring injuries) the Cowboys turned to rookie DeVonte Holloman at middle linebacker and undrafted rookie Cameron Lawrence on the weak-side.

The Packers were able to dominate in the second half, putting up 299 yards on offense, 19 first downs and scoring 34 points.

"Those guys tried to hang in there the best they could," coach Jason Garrett said. "There are some things they did well and obviously some things they will learn from."

The Cowboys might need them to learn in a hurry. Lee is considered "week to week," with his sprained ligament in his neck. Carter could need more time as well and Durant had missed three games with a hamstring injury.
