This news in from Steve Corkran, who is in Napa with no internet access right now:
Terrelle Pryor is wearing No. 6 and taking some reps at quarterback now for the Raiders. Also, just-signed Lito Sheppard is also participating in drills. Sheppard is donning Nnamdi Asomugha’s old No. 21 jersey.
To make room for both Pryor and Sheppard on the roster, the Raiders have released ex-San Jose State quarterback Jason La Secla as well as offensive lineman Alan Pelc.
