Soler's MRI on Monday revealed he has a Grade 1 oblique strain, Jeffrey Flanagan of MLB.com reports.
Soler's MRI confirmed what was reported earlier, so the 25-year-old will sit for the next week before slowly being eased back into baseball activities, ensuring that he will miss some time to start the season. His absence could open up a spot for speedster Terrance Gore to make the team as a reserve outfielder, while Paulo Orlando should see the bulk of the time in right field as Soler's primary replacement.
