Former Cubs outfielder and current National Kyle Schwarber left Friday's game against the Dodgers with an apparent right leg injury.
Schwarber singled to center field in the second inning but pulled up at first base. He appeared to roll his ankle before grabbing the back of his right leg.
Schwarber walked gingerly off the field with a Nationals trainer and manager Davey Martinez.
The Cubs non-tendered Schwarber after six seasons this past offseason. He's been the hottest hitter in baseball the last few weeks, hitting 16 home runs in an 18-game span.
MLB named Schwarber the NL Player of the Month for June earlier Friday.
