The 49ers formally announced the signing of free agent wide receiver Mario Manningham Thursday morning.
Manningham (6-0, 185) was selected by the Giants in the third round (95th overall) of the of the 2008 draft. Over his four-year career, Manningham has played in 49 games (28 starts) and has recorded 160 receptions for 2,315 yards and 18 touchdowns.
"We are very pleased to add a player like Mario to our team," said 49ers general manager Trent Baalke said in a statement. "Although it is still early in his NFL career, he is a productive wide receiver with a lot of big game experience. He will be a nice compliment to our current wide receiver group and a good fit for our offensive system.
Manningham will join a receiving corps that includes Randy Moss, who signed a one-year contract last week, and Michael Crabtree, who had 72 receptions for 874 yards and four touchdowns in 2011.
