Cowboys practice report: Day 5

OXNARD, Calif. -- The Cowboys' first two-a-day practice was marred by the loss of starting left tackle Kyle Kosier. During the middle of practice the Cowboys took off their shoulder pads and conducted things at a slower tempo.

*Injury report: Kosier left with a sprained right knee and an MRI is scheduled to determine the his long-term status. Also linebacker Jason Williams left practice briefly with a leg injury, but returned. Martellus Bennett missed the morning practice, but said he should return for the afternoon. He's coming back from an ankle injury. Keith Brooking also missed the morning session, but will be back in the afternoon.

Stephen Hodge (knee), Marcus Spears (knee), Jesse Holley (hamstring), Alex Barron (ankle), Marc Colombo (knee), Scott Sicko (concussion) and Dez Bryant (ankle) missed practice. Holley and Sicko were doing some heavy running. For the second consecutive practice, Pat Watkins did individual drills.

*Backup tight end DjLeon Farr had a long morning practice. He was called for two false starts and he dropped a touchdown in the end zone. The pass hit him in the chest. Meantime, Jason Pociask was looking pretty good. He caught a touchdown pass in the corner for Jon Kitna and was blocking and running his routes well.

*It may be nothing, but it's worth noting that fullback Chris Gronkowski is getting plenty of reps with the first-team offense. Deon Anderson is doing a nice job when he's in there, but the coaches want to see Gronkowski become physical at the point of attack. Running backs coach Skip Peete said he wants Gronkowski to seek out defenders to wack them instead of just waiting for them to come to him.

*The Cowboys ran a Razorback play for the fourth time in training camp. Tashard Choice took the snap up the middle and ran for about five yards. Tony Romo was lined up as the wide receiver.

*Terence Newman did a nice job on a high throw from Kitna to intercept a pass.

*Montrae Holland did a nice job blocking Anthony Spencer on a run by Herb Donaldson.

*Victor Butler had a strong practice. He made a nice tackle for loss on Marion Barber and he sacked Tony Romo. Romo was so mad at the sack he threw the ball up in the air.
