"At first, it didn't really register that it stabbed me," he said. "It just felt like it knocked the breath out of me. I kept on going and once I touched home, [Jeff] Samardzija was like, 'Are you OK?' and I said, 'Yeah, I just got the wind knocked out of me.' He said, 'No, dude, you're bleeding.'"
Colvin was hospitalized and eventually went home for the remainder of the season.
"It stinks because we're playing so well now and I wish I could be a part of that," he said.
His injury has prompted discussion on whether Major League Baseball should ban maple bats.
"I can't say much about it because I use maple bats," Colvin said. "There's nothing to say about it. It happened and Major League Baseball is doing a good job to reduce the number of broken bats and I think they'll keep working on it to get it better."
Would Colvin consider changing to ash or birch or something else?
"No, not really," he said. "If somebody really made me, I guess I'd have to. It's a bat and they're going to break. I've seen ash bats break like that before. As long as they keep trying to improve them and make them better, I don't see what's wrong with them."
Colvin can start jogging now, but no heavy weight-lifting. No swimming, no flying. He's getting married in early November, and the doctors did give Colvin the go-ahead to go on his honeymoon.
The incident hasn't made him fearful. He is eager to get back on the field.
"I'm going to go out and play the same way I always do," Colvin said. "It's not going to scare me to go out on the field again, if that's what you're implying."
