Report: Cowboys' rookie OT out for season

Posted by ESPN.com's Matt Mosley

Cowboys rookie right tackle Robert Brewster, a third-round pick, will miss the '09 season with a torn pectoral muscle, according to Todd Archer of the Dallas Morning News. Brewster apparently suffered the injury during offseason workouts following the club's June minicamp.

It's bad news for a team that has done a poor job of developing depth along the offensive line. Brewster didn't miss a game in four years at Ball State, but an AFC scout told me after the draft that he was very worried about Brewster's durability leading up to the draft. Brewster's agent tried to put a positive spin on things by saying that rookie linemen don't normally play anyway, but the Cowboys definitely needed Brewster to be in camp improving his technique.

It's also a huge setback that Brewster won't be able to focus on his upper body strength for awhile. That's an area in which he desperately needed to make strides. The Cowboys didn't expect any of their draft picks to immediately become a starter, but Brewster had a chance to help on special teams and provide much-needed depth.

Now the Cowboys will continue to see if former draft picks Pat McQuistan and Doug Free can challenge for playing time. Yes, they're still on the roster. So is someone named Gibbons. If you need a unit to worry about for the Cowboys, I suggest you start at the offensive line. The Cowboys could be one injury away from having some serious issues.

OK, I'll keep you posted.
