Safety Tyvon Branch may have suffered a fractured fibula, according to an ESPN report Monday.
Branch left was helped off the field in the first quarter of Sunday’s 19-9 win over the Jacksonville Jaguars, with coach Dennis Allen saying after the game it was thought to be a “significant’’ injury.
The last time Allen used “significant’’ in assessing an injury, left tackle Jared Veldheer needed surgery to repair a torn triceps.
According to a tweet from ESPN’s Adam Schefter, “Oakland S Tyvon Branch suffered what Raiders say is “significant’’ injury thought to be a fractured fibula that will sideline him indefinitely.
Brandian Ross filled in for Branch against Jacksonville, with Usama Young also able to play both safety spots for the Raiders. Ross had a sack against the Jaguars and Young 1.5 sacks.
Allen is scheduled to meet with the local media at 1 p.m.
When ESPN reported that tackle Menelik Watson had underwent arthroscopic knee surgery last week, Allen declined to confirm, citing team policy.
