The Raiders will officially be without their starting left tackle and tight end for their season opener.

The Raiders will be without starting left tackle Menelik Watson and starting tight end David Ausberry when the team travels to Indianapolis for the 2013 season opener head coach Dennis Allen announced Friday.

Watson was taking over for injured left tackle Jared Veldheer who is expected to be placed on partial season injured reserve with a triceps injury. In Wednesday's practice Watson tweaked his knee and couldn't finish. He was replaced at left tackle by Khalif Barnes. Barnes has experience at left tackle but hasn't played at the position for three seasons. Replacing Barnes spot at right tackle will be recently acquired Tony Pashos.
