"Manny Acta said outfielder Shin-Soo Choo might be back in a week. Choo, recovering from a broken left thumb, started his rehabilitation assignment at Class A Lake County on Monday.

"Assuming everything works out well, and [Choo] feels comfortable, I would say he'd need a week of rehab games," said Acta. "Still, we're going to have to evaluate it every day. He has to feel comfortable."

Choo was in Lake County's lineup at DH on Monday and had Tuesday off.

"Eventually, he'll move up the ladder [Class AA Akron, Class AAA Columbus] so he can face better pitching," said Acta. Choo's last game with the Tribe was June 24, when San Francisco's Jonathan Sanchez hit him with a pitch.

The story is different with Grady Sizemore, recovering from a bruised right knee and a hernia operation. Acta said Sizemore would not be back this month and would not say when, or if, he'd be back in September.

Sizemore is scheduled to start playing catch and swinging the bat this weekend. His last game was July 17, when he bruised his knee at Camden Yards going around first base.

"Grady won't be back this month," said Acta. "We never anticipated him to come back this month." "
