The Cowboys will be without 27-year old strong safety Gerald Sensabaugh and 34-year old inside linebacker Keith Brooking for the next three weeks.  Sensabaugh temporarily dislocated his left shoulder over the weekend while Brooking has a mild sprain of the AC joint in his right shoulder.  Sensabaugh played in the first 3 pre-season games for the Cowboys and he had 3 tackles.  In his first season with the Cowboys in 2009, Sensabaugh played in 15 games (all starts) and he finished up with 66 tackles, 8 passes defensed and 1 interception.  Brooking also played in the first three pre-season games for the Cowboys and he had 5 tackles and 1 pass defensed.  Last year was also Brooking’s first with the Cowboys.  He played in 16 games (14 starts) for the Cowboys last season and he had 106 tackles, 3 sacks and he defensed 7 passes.  Brooking and Sensabaugh are really important to the Cowboys’ run defense so they hope both of them will be ready for the season opener against the Redskins.
