The move is retroactive to April 2, making Jimenez eligible to return on April 17, the Rockies said in a statement.
"We're trying to take care of it right now, trying to make it 100 percent ready," Jimenez told reporters.
"I don't want to be 50 percent or 70 percent, then by the time I get to the mound and start throwing again, (the injury) is going to come back."
Jimenez, 27, pitched the Rockies' first ever no-hitter last season, beating the Atlanta Braves 4-0.
The right-hander went on to compile a 19-8 record with a 2.88 earned run average.
