The 49ers remain interested in former Colt Austin Collie, but they are unlikely to make a move on the free-agent wide receiver until after training camp begins, a source close to the situation said this week. One of the team's top priorities this summer will be to see if any of their young and inexperienced wideouts perform well enough to warrant significant snaps when the regular season begins. If none elevates his game, an inexpensive veteran like Collie would be of interest. Collie, who played at Oak Ridge High outside of Sacramento, worked out for coaches and scouts on June 13. He has recovered from a torn pattela tendon that cost him most of the 2012 season in Indianapolis, and he has passed all the neurological tests associated with concussions. Source: SacramentoBee
