The exam was done Wednesday after Street felt tightness in his shoulder. He felt fine after throwing 25 pitches Monday in a simulated game, but felt tightness in the shoulder while playing catch Tuesday and underwent the MRI exam the following day.
"It's as good a news as we could've hoped for," Street said. "No structural damage. Now it's just trying to build back up again and try not to have any more flare-ups and get on a mound and develop a routine."
Street will open the regular season on the disabled list. He said he asked trainer Kevin Dugger when he might expect to be able to pitch for the Rockies, and wasn't surprised to get a vague response.
"The answer I knew I was going to get was we move slowly and get healthy," Street said.
Street will not appear in any Cactus League games this spring. He threw batting practice for the first time Feb. 26, the first day of Rockies full-squad workouts, and developed tightness in his shoulder the following day.
Street signed a three-year, $22.5 million contract after he converted 35 of 37 saves last season.
