SANTA CLARA -- Wide receivers Lavelle Hawkins and Austin Collie took the practice field Friday evening as the newest members of the 49ers.
Hawkins and Collie impressed the 49ers during a Friday tryout that included veteran free agent Laurent Robinson. The 49ers signed both players to one-year contracts to provide more depth and competition for their thinning corps of wide receivers, the team announced.
The 49ers waived center Sherman Carter and punter Colton Schmidt to make room on their 90-man roster for Hawkins and Collie.
The 49ers have been down five wide receivers from their 90-man roster. Kyle Williams, A.J. Jenkins and Kassim Osgood have missed multiple practices due to hamstring strains. Michael Crabtree (Achilles) and Mario Manningham (knee) are on the physically-unable-to-perform list. The 49ers expect to get some of their injured players back for practice on Sunday.
In addition, rookie Quinton Patton has been able to practice but has not been catching passes due to a injured left middle finger.
Hawkins asked for his release from the New England Patriots on Wednesday, a source said. The Patriots signed Hawkins (5-foot-11, 195 pounds) in May. He played his first five NFL seasons with the Tennessee Titans after the club selected him in the fourth round in 2008 draft.

An ankle injury limited Hawkins to just seven games last season. He caught five passes for 62 yards. In 52 career games, Hawkins has 71 receptions for 771 yards and one touchdown. The Titans released him in May, and he signed with the Patriots a week later.
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 also has a history of concussions.

Collie (6-0, 204) 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.
