Chicago Cubs outfielder Tyler Colvin reassured fans Monday that he's doing OK a day after a scary incident in which his chest was punctured by a piece of a broken bat.

Colvin remained in stable condition at Jackson Memorial Hospital in Miami, where he's expected to remain a few days for observation.

Baseball commissioner Bud Selig said he spoke with Colvin.

"Hopefully he's going home tomorrow," Selig said. "It scared me."

With Colvin on third base during Sunday's game against the Florida Marlins, Cubs catcher Welington Castillo hit a ball to left field. Colvin watched the ball, and he didn't see a large chunk of the shattered bat heading toward him. The bat punctured the upper left side of his chest. The team said there was minimal external bleeding, and he was being treated with a chest tube to prevent a collapsed lung.

"I want to thank Cubs fans for their support all season, especially right now, and let everyone know that I'm doing OK," Colvin said in a statement. "I also want to thank everyone who has helped take care of me here in Miami -- the Cubs and Marlins training and medical staffs, the EMTs at the ballpark and everyone here at the hospital."

The 25-year-old rookie will miss the remainder of the season. He hit .254 with 20 home runs and 56 RBIs.

"You never want to have a season end early, and I'm disappointed that I'm not going to be able to make it through the finish line with the rest of my teammates," Colvin said. "That being said, I couldn't be more thankful for the Cubs organization, my teammates and the opportunity to play for Cubs fans my rookie season. Thank you from the bottom of my heart."
