The 23-year-ld played catch early Monday afternoon, and the club is confident he will be back in the rotation this weekend.
"He did fine, there were no ramifications whatsoever," Rockies manager Jim Tracy said. "Moving forward there's a real good chance we'll line him somewhere over the weekend against Cincinnati if things continue to trend themselves in the way they are going."
As for who will make the spot start Tuesday for the Rockies, Tracy wasn't ready to make an announcement before Monday's game.
Pomeranz, who is 1-5 on the season with a 4.98 ERA, also reported feeling better after throwing.
"It felt good today," he said. "Felt a little better with a couple days off, we'll see how it feels tomorrow."
