Cowboys cut Marc Colombo, 8 others

SAN ANTONIO -- The Dallas Cowboys made official on Thursday what was learned a few days ago: They released Roy Williams, Marion Barber and Leonard Davis, and they also parted ways with right tackle Marc Colombo.

The Cowboys informed the players of the moves on Tuesday; however, the decision on Colombo was put on hold as the Cowboys worked through negotiations with Doug Free and Kyle Kosier. The Cowboys never approached Colombo about reducing his contract, according to sources.

Kicker Kris Brown, offensive linemen Robert Brewster and Travis Bright, linebacker Kelvin Smith and wide receiver Troy Bergeron were also let go.

The moves save the Cowboys roughly $18 million in salary cap space in 2011 but will carry over more than $20 million in dead money on the 2012 salary cap.

By cutting Williams, Barber, Davis and Colombo the Cowboys are ushering in a new era on the offense. Dez Bryant will take over Williams spot and Felix Jones is now the unquestioned starter at running back. Colombo will be replaced by rookie Tyron Smith, who signed a four-year deal worth $12.5 million on Thursday.

Veteran Montrae Holland is in line to replace Davis but the team could still make a move for a veteran interior linemen.
