Manningham's shoulder injury tests 49ers' depth

ST. LOUIS -- The 49ers compensated for the losses of receiver Kyle Williams and running back Kendall Hunter with a little more Ted Ginn and Brandon Jacobs.Now, receiver Mario Manningham's status is uncertain after sustaining a shoulder injury that forced him out of action in the fourth quarter of the 49ers' 16-13 overtime loss to St. Louis Rams."We won't know right away in terms of how that will affect him next week," 49ers coach Jim Harbaugh said.Manningham has been nursing a right shoulder injury since originally being injured Oct. 14 against the New York Giants. He missed one game due to the injury.Williams (knee) and Hunter (Achilles) were placed on season-ending injured reserve last week. On Sunday, the 49ers suited up rookie A.J. Jenkins for the second time this season. But Jenkins and backup quarterback Alex Smith were the only 49ers players who did not see action. Jenkins was the 49ers' No. 5 receiver in Sunday's game.Prior to Manningham's injury, the 49ers used Manningham, Ginn and Michael Crabtree in three-receiver formations against the Rams. Crabtree had strong game with seven receptions for 101 yards. Randy Moss saw action mostly in one-receiver sets.
Ginn had one reception for 1 yard. Colin Kaepernick's option pitch sailed over Ginn's head late in the fourth quarter. The miscue led to Janoris Jenkins' 2-yard fumble return.Frank Gore found it difficult to get anywhere against the Rams' defense, as he gained just 58 yards and a touchdown on 23 carries. Gore appeared to be favoring his left arm after a carry in overtime. Afterward, Gore said he was all right.Jacobs took over Hunter's role as the backup and managed just 6 yards on four rushing attempts. Rookie running back LaMichael James was not one of the 49ers' 46 active players.

Report: Former No. 3 overall pick works out for 49ers


Report: Former No. 3 overall pick works out for 49ers

The 49ers appear to have plenty of depth along their front seven, but the team brought in three defensive linemen for workouts on Tuesday, according to a source.

Two of those players are Tyson Jackson, the No. 3 overall pick of the Kansas City Chiefs in 2009, and former Steelers defensive end Ricardo Mathews, reports the NFL Network. The identity of the other player was not immediately known.

Jackson has been without a team since the Falcons released him in March with two years and $8.5 million remaining on his contract. He also worked out recently with the Los Angeles Rams.

Jackson, 31, spent his first five season in Kansas City before playing three years with the Falcons. He appeared in all 16 games last season, starting seven times, and recorded 13 tackles and no sacks.

Mathews, 30, took part in his second workout with the 49ers, according to the report. A seventh-round draft pick of the Indianapolis Colts in 2010, Mathews appeared in 16 games with five starts for the Steelers last season after signing a one-year contract for the veteran minimum. He spent the previous two seasons with the Chargers. 

The 49ers have an abundance of defensive linemen, or players capable of rushing the passer from a position along the defensive line, such as DeForest Buckner, Arik Armstead, Solomon Thomas, Earl Mitchell, Elvis Dumervil, Aaron Lynch, Chris Jones, Tank Carradine, Quinton Dial, Ahmad Brooks, Eli Harold, Ronald Blair and D.J. Jones.

However, the 49ers were down three defensive linemen last week due to injuries to Buckner (ankle), Lynch (ankle) and Blair (groin). The 49ers have one opening on their 90-man roster.
