Add another disappointing chapter to the unfulfilled career of Cleveland Indians outfielder Grady Sizemore. The team announced on Tuesday that Sizemore, who has yet to play a game in 2012, will indeed miss the remainder of the 2012 season after not progressing in rehab like the team hoped he would. Sizemore underwent knee surgery in late 2011 and back surgery in spring of 2012, and has not been able to get back to 100%.

Sizemore returned to the Indians in 2012 on an incentive-laden contract that tied much of his salary to his health, and it's fair to wonder if any team will take a chance on him for the 2013 season. Sizemore has only played in 104 games since the beginning of the 2011 season.
