It is likely to be August before the Marlins see Josh Johnson on a mound for them. But that outcome was far less discouraging than the other possibility: not seeing Johnson at all the rest of the season.

A MRI performed Wednesday on Johnson's injured right shoulder revealed no structural damage, and the pitcher will now rest the arm for the next seven to 10 days before resuming his throwing program.

Johnson's agent, Matt Sosnick, said the pitcher was "very" relieved with the diagnosis after being examined in Alabama by Dr. James Andrews. Johnson received a cortisone injection.

Johnson, who has been on the disabled list since mid-May with shoulder inflammation, complained of discomfort after throwing a bullpen session Friday in Jupiter.
