Tulowitzki has been rehabbing after left groin surgery and playing for the Rockies' minor league affiliate, Double-A Tulsa, for three games, and is expected to join Triple-A Colorado Springs for the next three days. Yet, according to the article, his ultimate return to the majors remains uncertain as he and the team are preferring to err on the side of caution.
Here's Tulowitzki on the recovery process, from the story:
"It's just (being) timid, making sure, playing safe," he said. "The last time I went on rehab, I came back and got hurt again, so that stuck in my mind a little bit. But each game I played I got a little bit better.
"It's going to be a slow process, I know that."
The All-Star shortstop's groin injury initially flared up in May and wound up requiring surgery in late June.
