Ross could return to the Red Sox by the middle of next week if all goes well.
Ross was with the club in Miami earlier this week and clearly looked antsy to get back to work.
"Yeah, baseball is his life," said Red Sox manager Bobby Valentine. "He loves it. He didn't like not playing."
When Ross returns, the Red Sox could have some interesting decisions to make. It might be hard to continue playing Adrian Gonzalez in the outfield while having David Ortiz, Kevin Youkilis and Will Middlebrooks all in the lineup if Ross is also available.
"We'll see," said Valentine. "We'll see who else is in the mix when he comes back."
