Matt & Mindi: Why did 49ers bring in Austin Collie?

SANTA CLARA -- Veteran wide receiver Austin Collie, who worked out Thursday afternoon for the 49ers, left the team facility without a contract offer.
"It's still ongoing," 49ers coach Jim Harbaugh said. "There are still a few more things we want to have checked out."
The 49ers lost another wide receiver off the team's 90-man roster upon news that first-year player Brandon Carswell, who signed Wednesday, sustained a torn ACL in his right knee during a non-contact drill early in his first practice with the team.
When asked if the 49ers will add another wide receiver for training camp, which opens in late-July, Harbaugh answered, "Yeah, it's a possibility."
It's uncertain whether Collie is a legitimate option at this stage. The 49ers brought Collie in for a workout to check on his physical condition. He played in just one game for the Indianapolis Colts last season after sustaining a torn patellar tendon in his right knee.
"He had a patellar tear 7 1/2 months ago and he's very far along," Harbaugh said. "It's pretty impressive."
Collie also has a history of concussions. When asked if that's still an issue, Harbaugh said, "That's for the doctors to look at and analyze."
Collie, who has received medical clearance to return to action, worked out earlier this week for the New England Patriots. He is expected to take other visits.
