Danny Amendola out indefinitely?

St. Louis Rams wide receiver Danny Amendola reinjured his triceps during practice last week and will visit a specialist on Monday, according to team sources.

The concern is he could be out indefinitely. Amendola is out this week versus the Washington Redskins, but that was the Rams' expectation anyway.

Amendola, the Rams' reception leader last season, hasn't played since dislocating his left elbow in the opener against the Philadelphia Eagles and didn't practice Friday.

In Sunday's game, St. Louis Rams guard Jacob Bell and backup defensive tackle Gary Gibson were sidelined by injuries in the first half.

Bell hurt his left hamstring and Gibson hurt his right hip. Tony Wragge replaced Bell.

The Rams remained winless, losing 17-10 to Washington.
