But Young -- who was diagnosed with a left intercostal muscle strain after striking out on a check swing against Miami's Josh Johnson on Sunday -- said he was feeling much less pain on Monday and that a stint on the disabled list was unlikely.
Manager Jim Tracy said the team will make an official decision on Tuesday as to whether Young will land on the disabled list, but took Young's improvement as a very good sign.
"He has a tendency to respond very quickly, and yet this situation with regard to this type of injury is one that doesn't cooperate for a player too well," Tracy said. "If he's still sore tomorrow, then we've got to figure some things out."
Tracy said his biggest concern regarding the injury was the diagnosis -- injuries surrounding the oblique have a tendency to linger and are susceptible to aggravation.
"We're milking this a little bit to see exactly where he's going to go, but it's safe to say that he's sore today and that we have some concern," Tracy said. "But we're going to give it another day and see what it progresses to, or if some of the soreness subsides and he's able to start moving around a little bit."
Any time Young will miss will be a big blow to the Rockies -- Young is hitting .406 in August (26-for-64) with 10 multihit games. Charlie Blackmon -- who was called up on Saturday to fill in for Carlos Gonzalez's stint on the bereavement list -- batted leadoff for the Rockies on Monday.
"You can't control something like this, so you just get it right and get ready to go again," Young said.
