Wheeler (shoulder) will remain behind in Florida to pitch in a minor-league scrimmage Thursday, Matt Gelb of The Athletic reports.
Wheeler has been delayed by shoulder soreness this spring but appears set to avoid the injured list. Following Thursday's outing, he'll be lined up to start the fifth game of the season, which comes against the Mets on April 12. He's expected to throw around 60 pitches Thursday, so he may not throw much more than 75 in his regular-season debut.
