Michael Conforto has a concussion

The second player of the day to be lost to injury, Michael Conforto collided hard with Robinson Cano on fly ball to shallow right field in the fifth inning of today’s game against the Nationals. He hit the ground hard and stayed down in the grass for a few moments before getting up slowly, seeming dazed. After a lengthy conversation with the trainer and Mickey Callaway, Conforto exited the game.

After the game, the Mets announced that Conforto has been diagnosed with a concussion. He will head to New York by train for further evaluation to determine the severity of the concussion.

Until then, it’s hard to know how much time Conforto will miss. Sometimes players come back from a concussion after about a week or so, but we have also seen concussions that lead to prolonged absences or even stalled careers. Either way, it’s a rough day for the Mets, who have lost two of their best hitters on the same day. Heading into today’s game, Conforto had accrued 1.6 fWAR—the highest mark on the team—and posted a 148 wRC+ over 178 plate appearances.
