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. Collie has suffered three of them since entering the NFL in 2009. One of the 49ers team doctors, Daniel Garza, is a specialist at Stanford Hospital in concussions and head injuries.
Collie, who played at BYU, has been training in Utah this offseason. He also has had a workout with the Patriots.
Wide receiver, meanwhile, became the 49ers' biggest offseason question mark when Michael Crabtree suffered a complete tear of his right Achilles' heel on May 21. The team's leading receiver a year ago - and the first 49ers wideout to surpass 1,000 receiving yards since Terrell Owens in 2003 - Crabtree will miss at least the first three months of the season.
Veteran Anquan Boldin is entrenched at one starting spot. The 49ers are looking for someone at the other spot. The candidates include A.J. Jenkins, Ricardo Lockette, rookie Quinton Patton and Marlon Moore. Also, Kyle Williams promises to be back at practice after recovering from an ACL tear in late November.
The 49ers might add depth at wide receiver before training camp. They signed Brandon Carswell last month only to see him immediately go down with an ACL injury. The team has an open roster spot and will have more once Crabtree, rookie running back Marcus Lattimore (knee) and others are placed on the Physically Unable to Perform or non-football injury lists.
**UPDATE** As predicted, the team claimed receiver Charly Martin off of waivers Friday. The 6-1, 212-pound Martin has spent time with the Chargers, Panthers, Jaguars and, most recently, the Seahawks before entering the league as an undrafted free agent in 2009.
