Oakland Raiders quarterback Bruce Gradkowski missed practice for a second straight day Thursday with an injured shoulder and running back Darren McFadden said he is questionable for Sunday’s game against the San Francisco 49ers with a hamstring injury. Gradkowski was knocked out last week after taking a hard hit on his shoulder from San Diego’s Shaun Phillips. He has only been able to watch practice this week and third-stringer Kyle Boller has been taking extra snaps in practice in case he needs to be the backup to Jason Campbell on Sunday. “There’s some improvement with Bruce, but unless he could work tomorrow, then we kind of know where we’re headed with it,†coach Tom Cable said. Cable said if Gradkowski is healthy enough to play he would likely be the starter on Sunday for the Raiders. McFadden will be the backup to Michael Bush if he is able to play. Source: Yahoo! Sports
