Add former Dolphins wide receiver Chris Chambers to the list of veterans the 49ers are working out today, according to a league source. Chambers, 33, started seven games last season for the Chiefs, finishing with 22 catches for 213 yards and one touchdown.
His best season came in 2005 when, as a member of the Miami Dolphins, he caught 82 passes for 1,118 yards and 11 touchdowns. The 49ers must replace Joshua Morgan (broken leg) on their roster, and they are looking at similarly-sized players with blocking ability. Chambers is listed at 5-11, 210 pounds and has been a member of teams -- the Dolphins, the Chargers and the Chiefs -- with excellent running games.
The 49ers also are trying out T.J. Houshmandzadeh, who is listed at 6-2, 202 pounds and who last year played for the run-heavy Baltimore Ravens. Practice squad players Joe Hastings and John Matthews also are in the running for the wide-receiver opening. Hastings, who has been with the team since training camp, has the edge over Matthews.
