SANTA CLARA -- With five wide receivers from the team's 90-man roster unable to practice due to injuries, the 49ers plan to look at some available free agents.
Laurent Robinson, whom the Jacksonville Jaguars released after one season, is expected to work out for the 49ers as early as Thursday, said a source, confirming a Boston Globe report.
It is not uncommon for the 49ers to work out players who are coming off of injuries. Robinson sustained four concussions last year. He is reportedly involved in a grievance against the Jaguars, who released him to avoid paying his $2.6 million salary for this season.
Robinson has also worked out recently with New England, the New York Jets, Detroit and Miami.
Robinson has played for Atlanta, St. Louis, Dallas and Jacksonville in his six-year career. His best season was in 2011 with the Cowboys, as he caught 54 passes for 858 yards and 11 touchdowns. Last year, he caught 24 passes for 252 yards in seven games with Jacksonville.
The 49ers might also bring back Austin Collie and other free agent wide receivers for a workout. Collie, who also has a history of concussions, sustained a season-ending torn patellar tendon last season while with the Indianapolis Colts.

The 49ers are running short on wideouts. Michael Crabtree is out until late in the season with an Achilles injury. Mario Manningham is still rehabbing an ACL tear he sustained in late-November.
Kyle Williams, A.J. Jenkins and Kassim Osgood have missed multiple practices due to hamstring strains.
When asked if any of the wide receivers have stepped up to take a lead in filling the starting job next to Anquan Boldin, 49ers offensive coordinator Greg Roman said, "I don't think anybody has pulled themselves out from the pack just yet. But guys are working hard and it's a healthy competition."
