ENGLEWOOD, Colo. (AP) — Derek Wolfe put in a full upper body workout in the weight room on Thursday, then the Denver Broncos defensive lineman thanked his teammates and fans for their prayers and well wishes after he was taken via ambulance from CenturyLink Field in Seattle last weekend.

Wolfe said he hopes to be back in the lineup by Denver’s Sept. 5 opener against Baltimore, less than three weeks after fears that he had suffered a cervical spine injury.

Wolfe said he holds no grudge against Seahawks fullback Michael Robinson, who slammed into him after he’d been cut by Seattle’s Luke Wilson on a running play. Wolfe’s head and neck were compressed by the hit and he lay on the turf for a couple of minutes in the silent stadium before being strapped to a backboard and being taken to a hospital.
