Per a report from Todd Archer at ESPNDallas.com, the Cowboys informed OT Robert Brewster, OG Travis Bright and LB Kelvin Smith yesterday that they were going to be cut. 

Obviously, these players are a lot further down the depth chart than Marion Barber, Roy Williams and Leonard Davis, who were all released yesterday. 

Brewster, a third round pick in 2009, spent most of last season on the practice squad and his release doesn't come as a surprise. Fellow practice-squadder Travis Bright had been contemplating retirement anyway and had not taken part in the team's player-led practices this season. Kelvin Smith was signed to the practice squad in December last year.

On a separate and perhaps more interesting note, it looks like Marc Colombo could return to the Cowboys on a reduced contract after he is officially released Thursday:

Colombo has expressed an interest in staying with the team and after a meeting with Cowboys owner/general manager Jerry Jones it was revealed he could with a reworked contract. Before Colombo's meeting with Jones, the team had told his agent, Jimmy Sexton, he was going to be released.
