Free-agent outfielder Grady Sizemore had microfracture surgery on his right knee in September and won't be ready for the start of the 2013 season, reports MLB.com.

Sizemore's agent, Joe Urbon, confirmed the surgery and says Sizemore won't be available until mid-season at the earliest.

Sizemore had the same surgery performed on his left knee in June 2010 while with the Cleveland Indians. Sizemore didn't play in 2012 after signing a one-year, $5 million contract with the Indians.

“He has a good mindset,” Urbon said. “He knows what to expect and what each step brings. “He has every intention of coming back when he’s 100 percent and not a day sooner."

Sizemore had an arthroscopic procedure performed on the knee near the end of the 2011 season, but the knee was a continual source of pain and frustration throughout 2012.
