Ravens guard Mulitalo has triceps surgery, out for year

The Baltimore Ravens remain undefeated following Sunday's comeback victory over the San Diego Chargers, but not unscathed.

Edwin Mulitalo Mulitalo

An MRI exam on Monday morning revealed that starting left guard Edwin Mulitalo suffered a torn right triceps tendon in the second half of the Ravens' 16-13 victory, and the eighth-year veteran underwent surgery later in the day to repair the injury. Mulitalo will be lost for the balance of the season.

The Ravens placed him on the injured reserve list Tuesday and and signed offensive guard
Ikechuku Ndukwe to their active roster.

Mulitalo, 32, left the game in the second half, with his right arm dangling at his side. There were concerns in the Baltimore locker room afterwards that Mulitalo's injury was serious.

Second-year veteran Jason Brown, a fourth-round choice in the 2005 draft who has appeared in just nine games, will replace Mulitalo in the lineup.

"Edwin deserved better," Ravens coach Brian Billick said Monday at his news conference. "But we have pointed out that the depth of this team should be one of its strengths. So this happens to be the first real test of that."

The loss of Mulitalo is a tough one for the Ravens, since he and perennial Pro Bowl tackle Jonathan Ogden form one of the NFL's best left sides. Although he has suffered through some inconsistencies in his career, Mulitalo is a powerful in-line drive-blocker who has approached Pro Bowl-level run-blocking at various stretches of his career.

The former Arizona standout was a fourth-round choice of the Ravens in the 1999 draft and has appeared in 106 games, starting 102 of them. Since 2000, his second season in the league, Mulitalo has averaged 15.0 starts and never started fewer than 14 games.

Brown's only regular-season start came last year when he filled in for Mulitalo in a Dec. 11 game at Denver. The Ravens face the Broncos at Invesco Field next Monday night.
