The Denver Broncos didn’t escape Saturday night’s preseason victory over the Seattle Seahawks without injury. Linebacker DJ Williams dislocated his right elbow in the first quarter of the 23-20 win, and is expected to miss 3 to 4 weeks. That would potentially put him on the sidelines for Denver’s first two regular season games. The Broncos will be feeling fortunate if another member of the defense doesn’t join Williams on the shelf for an extended period. Defensive tackle Broderick Bunkley left the game in the second quarter after injuring his knee on a cut block by Seattle guard Robert Gallery. The diagnosis was a sprained knee, but Bunkley was scheduled for an MRI to determine the full extent of the injury. The Broncos have already lost one defensive tackle, Ty Warren, to injury this preseason.
