Simmons uncharacteristically made a critical error that concluded the three-run ninth inning the Nationals needed to beat Craig Kimbrel and the Braves in Tuesday's first game. Gonzalez said he does not believe Simmons' neck influenced the fact that he was unable to glove Denard Span's game-ending grounder that rolled between his legs.
"We're so used to him making these plays and then all of the sudden he doesn't make a play and we think what is the matter with him?" Gonzalez said.
Simmons was available to play if necessary on Wednesday, and he should return to the lineup for Friday afternoon's series opener against the Cubs.
