SANTA CLARA -- (AP) The 49ers on Wednesday signed Ikaika Alama-Francis, a five-year veteran, to help a depleted group of linebackers.
The 49ers waived tight end Gijon Robinson, whom the club signed on Monday, to make room for Alama-Francis.
Alama-Francis, listed at 6-foot-5, 290 pounds, worked out for the 49ers early Wednesday afternoon. He was originally a second-round pick of the Detroit Lions in 2007. He appeared in just 19 games with the Lions, making two starts, before he was released. He has 47 tackles and one sack in 35 career games, including 16 games with the Miami Dolphins over the past three seasons.
Neither of the 49ers' starting outside linebackers has practiced this week. Aldon Smith is expected to be out of action for more than a week with a right hip bruise. Ahmad Brooks missed practices Monday and Tuesday with "general soreness," according to a source.
Draft picks Darius Fleming and Cam Johnson, both outside linebackers, are out of action. Fleming is likely out for the season after undergoing offseason surgery to repair a torn ACL. Johnson is also battling a knee problem that kept him out Friday's exhibition opener and the past three practices.
Alama-Francis is a graduate of Kalaheo High School and attended the University of Hawaii.
