After another blow to the linebacker corps Thursday with the career-ending spinal injury of DeVonte Holloman, the Dallas Cowboys again shuffled the deck in practice as they continued their search for their three top linebackers.

Rookie fourth-round pick Anthony Hitchens said he took all of the first-team middle linebacker repetitions in practice Thursday in front of veteran Rolando McClain, who was back practicing after he missed Wednesday with cramps. Hitchens was flanked by Justin Durant and Bruce Carter as first-team outside linebackers.

The Cowboys drafted Hitchens to be Sean Lee’s backup, but after they worked him at middle linebacker throughout the off-season they had him work mostly at weak-side linebacker in training camp. He’s spent this week back at middle linebacker.
