Cuts: Barber, Davis, Williams, Brown

The first thing the Dallas Cowboys had to do once the lockout ended was trim their roster so they could get under the salary cap. They appear to have wasted little time in doing so.

ESPNDallas.com reports that the Cowboys have informed running back Marion Barber, guard Leonard Davis and receiver Roy Williams that they will be cut. After a phone conversation I just had with the one and only Calvin Watkins, I believe the total savings toward the 2011 salary cap represented by those three moves comes out to $15.7 millon -- $6 million for Davis, $5 million for Williams and $4.7 million for Barber.

None of the cuts qualifies as a huge surprise, though there was some thought that Williams might represent too big a cap hit. But as Calvin reported Monday, designating Williams as a June 1 cut makes him a $5 million savings this year instead of a $12.9 million hit as we had previously thought. The question, of course, is who replaces Williams, who's been the object of scorn in Dallas because he's underperformed so drastically after they gave up so much to get him? Regardless of his performance, he did appear to be a pretty good No. 3 receiver behind Miles Austin and Dez Bryant, and they may have to fill that spot in free agency now.

Barber appeared to be a goner once the Cowboys drafted running back DeMarco Murray in April. Murray will take Barber's place in the running back rotation with Felix Jones and Tashard Choice. And if they're not prepared to start Montrae Holland, they will need a guard to replace Davis. They still need to re-sign left guard Kyle Kosier as well.

We're hearing conflicting reports on Marc Colombo, who'd be a $2.4 million savings, so stay tuned on that. And the Cowboys also cut veteran kicker Kris Brown, whose only projected function was to put training-camp pressure on David Buehler.

The Cowboys had been projected to be about $17 million over the cap, so this brings them close to the number. Still some work to be done (most likely in the form of restructuring deals) to make room for them to sign the free-agent safeties and defensive linemen they need. But they're clearly working on it.

Dallas also announced that its preseason game against the Chargers, which had been scheduled for Saturday, Aug. 20, will instead be played Sunday, Aug. 21 at 8 p.m. ET.
