Diaz's infection was caused by a splintered piece of wood that was surgically removed last month. He underwent a similar procedure in October, while dealing with the same issue.
In other injury-related news, Braves backup catcher David Ross said that he has started feeling some relief in his bruised right hand. Still, the club opted to further examine his hand via a CT-Scan that was performed on Saturday morning.
"He's good to go, but not very good to go," Braves manager Bobby Cox said.
If pressed into an emergency situation, Cox said he could use Brooks Conrad or possibly even Yunel Escobar at the catcher's position.
