The Nationals and Giants braved a slippery field on Saturday night and came out worse for wear after Bryce Harper sustained a knee injury while trying to beat out a grounder in the first inning. General manager Mike Rizzo announced Sunday morning that his star outfielder avoided structural damage to the knee.
Harper clutched at his left knee after going down and was attended to by trainers. Washington has around two months until the postseason begins, so that gives Harper plenty of time to get back to 100 percent.
The Nationals now have "no timeline whatsoever" for Harper's return, according to Rizzo.
Harper was hustling for a base hit, but went down and could not put any weight on the leg.
The Giants recalled utilityman Orlando Calixte to be their extra man. Games start at 10:05 a.m. PDT and 4:05 p.m. PDT.

"You're just thinking, 'Please, Lord, don't let it be serious'". "We're just hoping for the best".
Washington did not advance a runner to scoring position until the seventh.
Rizzo diagnosed the bone bruise as significant but said he is optimistic that Harper will return later this season. They will be opposed by Giants RHP Chris Stratton (0-2, 6.63) and LHP Matt Moore (3-12, 5.88).
