Norris day to day with bruised left forearm

OAKLAND -- A's catcher Derek Norris exited Friday's 4-3 win over the Red Sox after six innings with a bruised left forearm.

Ensuing X-rays proved negative on Norris, who took a foul tip to the arm and is considered day to day.

"It's no break," said Norris. "X-rays came back fine. There's nothing technically extremely wrong with it. I think it's just a pretty good contusion. We'll see how it feels tomorrow, how it bounces back."

Following Norris' departure, Stephen Vogt entered the game behind the plate, catching three scoreless innings from Oakland's bullpen.
