Branch an observer at Raiders practice

ALAMEDA, Calif. – Strong safety Tyvon Branch, who injured a shoulder in Sunday’s loss at Indianapolis, was an observer at practice Wednesday as the Oakland Raiders began preparations for their home opener against Jacksonville.

Two other projected starters who did not play against the Colts – rookie left tackle Menelik Watson (knee) and tight end David Ausberry (shoulder) – also did not participate. And kicker Sebastian Janikowski sat out practice to rest his right (non-kicking) calf.

Raiders coach Dennis Allen said he had no update on the condition of Watson, the team’s second-round draft choice, other than that he did not practice. Allen said that holding Janikowski out was a precautionary measure.
