SANTA CLARA -- Veteran wide receiver Austin Collie is scheduled to work out for the 49ers on Thursday, a source told CSNBayArea.com.
Collie will join free agent Laurent Robinson, as the 49ers look to keep tabs on a couple of wide receivers who are coming off injuries last season. The 49ers might have another receiver or two take part in the workout, too.

Collie, 27, previously worked out for the 49ers in June, at which point he was 7 1/2 months removed from a season-ending ruptured patellar tendon. Collie and Robinson both have a history of concussions.
Collie played in just one game with the Indianapolis Colts in 2012. He has recorded 173 catches for 1,845 yards and 16 touchdowns in his four-year career.
The 49ers have been down five wide receivers on the practice field. Michael Crabtree (Achilles) and Mario Manningham (knee) are on the physically-unable-to-perform list, while Kyle Williams, A.J. Jenkins and Kassim Osgood have each missed multiple practices due to hamstring strains.

Robinson, 28, has played for Atlanta, St. Louis, Dallas and Jacksonville over six NFL seasons. Last year, he was limited to seven games due to four concussions while with the Jaguars. He caught 24 passes for 252 yards and no touchdowns one season after recording career-bests with 54 receptions for 858 yards and 11 touchdowns with the Cowboys in 2011.
