"How long will Grady Sizemore be out of the Indians' lineup this time?

So far, his injury is still being described as the same bone bruise of the right knee that put him on the disabled list from May 12 to May 27. But Sizemore was sent back to Cleveland on Monday for further evaluation after he was placed on the 15-day DL again.

The Tribe lineup is painfully thin without Sizemore and Shin-Soo Choo, who probably will remain on the DL until early September with a broken thumb.

"Grady plays through pain all the time," manager Manny Acta said. "He's done that the last three years pretty much. It's very hard for him not to be out there with his teammates, and it's hard for us, too."

Sizemore reinjured his knee in the first inning of Sunday's 8-3 loss to the Orioles at Camden Yards, when he made the turn at first on his way to second with a double. A bone bruise (which is inside the bone) can become aggravated without bumping the knee or having the knee involved in a collision.

Ever since he returned from the DL, Sizemore probably has been playing with some discomfort.

"I'm not 22 anymore," he said over the weekend, before tweaking the knee. "I never really feel 100 percent. But I feel good. The last two months everything has been moving forward.""
