"I'm obviously sorry to my teammates because I feel like I'm letting them down more than anything, [and] the organization," Tulowitzki said. "Hopefully, it's not too long before I'm back out there, but it's hard to take."
At a news conference held before Saturday's game, Tulowitzki said he wasn't angry with manager Clint Hurdle for taking him out, but frustrated with his play this season. In 39 games, he's hitting .166 with three home runs and 16 RBIs.
"I don't know if it was just that game or just built up frustration," Tulowitzki said. "The last thing you want to do in that situation is come out of the game when you feel like your team has a chance. You want to be out there on the field to make a play or come up with that big hit."
This is the second time Tulowitzki has gone on the disabled list this year. He missed 46 games rehabbing from a torn left quadriceps that he injured on April 29.
This injury comes at a particularly bad time for both Tulowitzki and the Rockies. The injury dampens some of the momentum the Rockies had built from back-to-back dramatic victories, and it halts the progress Tulowitzki has made since coming back from the leg injury on June 20.
Tulowitzki's average had risen 14 points in the 13 games he's played since returning, and he had five doubles and five RBIs.
"[This injury] is tougher to take," Tulowitzki said. "The other injury is baseball-related. This one's a stupid injury that I could have prevented."
Tulowitzki spoke with Hurdle on Saturday morning about the incident and said Hurdle was very supportive.
"He's put himself in a challenging position," Hurdle said. "He's got a lesson available to be learned."
Tulowitzki said he is not allowed to sweat for the next two days because of the stitches, but after that he will exercise to stay in game shape. He said he hopes to have the stitches removed after two weeks, when he can begin throwing and hitting.
"I need to control myself better," Tulowitzki said. "Next time, I'll handle the situation different. I messed up on my part and I'm willing to take blame for it."
Smith is making his second stint with Colorado this season. He played 12 games with the Rockies from May 24-June 8, hitting .262 with a home run and three RBIs.
Smith was recently named to the Pacific Coast League All-Star team after hitting .323 with 10 home runs and 53 RBIs in 68 games for the Sky Sox.
"He's probably swinging the bat the best down there, other than Joe [Koshansky]," Hurdle said. "And it gives us another left-handed bat."
