Syndergaard (biceps) played catch before Friday's game, which could determine whether he starts Sunday, James Wagner of The New York Times reports.
Manager Terry Collins said he expects Syndergaard to be able to make his scheduled start against the Nationals, but wants to see how the ace feels after some light throwing. Sean Gilmartin was recalled Friday and could take his spot in the event of any setbacks. Expect more information from the team soon.
