SANTA CLARA The 49ers remain interested in former Indianapolis 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.
The source spoke on condition of anonymity because he didn't have authority to speak on the matter.
One of the team's priorities this summer will be to see if any of its young, inexperienced wideouts perform well enough to warrant significant snaps when the regular season begins. If none proves himself worthy, an inexpensive veteran such as Collie would be of interest.
Collie, who played at Oak Ridge High School, worked out for coaches and scouts June 13. He has recovered from a torn patella 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 concussion and head injury specialist at Stanford Hospital.
Collie, who played at BYU, has been training in Utah this offseason. He also has had a workout with the Patriots.
Wide receiver became the 49ers' biggest offseason concern when Michael Crabtree tore his right Achilles' tendon May 21. The team's leading receiver a year ago 85 receptions for 1,105 yards and nine touchdowns Crabtree will miss at least the first three months of the season.
Veteran wide receiver 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 (Natomas High). Also, Kyle Williams hopes to return to practice after recovering from a late-November ACL tear.
The 49ers might add depth at wide receiver before training camp. They signed Brandon Carswell last month, but he went down with an ACL injury. The team has an open roster spot and will have more spots when Crabtree, rookie running back Marcus Lattimore (knee) and others are placed on the physically unable to perform or non-football injury lists.
