MONTREAL -- Jenrry Mejia, who was struck in the right forearm in the fifth inning Friday, did not suffer any fractures as a result of the blow.
The Mets announced Mejia's X-rays, which were taken late Friday, were negative.
"Just inflammation," Mejia said.
Pitching coach Dan Warthen separately indicated the bunion on Mejia's right big toe was a non-issue Friday against the Toronto Blue Jays.
The Mets are expected to announce their 25-man roster after Saturday's exhibition finale -- comfortably ahead of MLB's noon Sunday deadline.
Given the Mets are prepared to announce their team without knowing how Mejia's forearm ultimately will respond, it would seem logical to conclude that Daisuke Matsuzaka should be named to the Opening Day roster and start Game 4 of the season, Friday against the Cincinnati Reds at Citi Field.
Jonathon Niese remains on track to come off the DL and start two days later against Cincinnati. If Mejia is optioned to the minors on the eve of the season, John Lannan would be the hedge against Niese having a setback.
