The Cowboys will likely be without Terrell Owens when they face the Redskins this weekend, but are expected to have fellow wide receiver Terry Glenn back on the field.  “T.O.” suffered a high ankle sprain in the team’s 20-13 win over the Panthers Saturday.  The Cowboys are expected to rest Owens for the regular-season finale in Landover, then will have another week to rest the star wide out.  Dallas has clinched the top seed in the NFC playoffs, and will have a first-round bye.  Glenn has not yet played this season.  In September, the 33-year-old underwent two arthroscopic procedures to repair cartilage damage in his right knee.  He also had a cyst removed.  Glenn had 1000-yard receiving seasons in each of the last two campaigns.
