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.
