The game had been delayed due to heavy rains and it still was sprinkling when the game began.
Haper stayed on the ground in serious pain, and had to be helped off the field.
The Nats now hold a 14-game lead in the National League East and have the third best record in baseball overall, so even if they lose Harper for the rest of the regular season, it's not likely they fall to the bottom of the rankings.
When Harper left the stadium, he was walking on his own power in the Nationals' clubhouse around 1:45 a.m. Sunday morning after a 3-1 win by the Nationals over the San Francisco Giants.
The news could have been much worse for Bryce Harper and the Nationals. The 2015 NL MVP is 10-for-28 with two homers, seven RBIs and six runs scored in his last seven contests, but went 0-for-8 with four strikeouts during Washington's three-game sweep of San Francisco.
Harper, an All-Star in 2017, is having a bounce-back season after some regression last season. "I couldn't get the ball down in the first inning".
Harper's loss will be felt by a team that is on pace to win 97 games yet will enter October as nobody's favorite because of the historic dominance that has happened at Dodger Stadium this season. "I'm very optimistic that he'll be at least fine shortly". This is his first stint on the disabled list since 2014.
Taylor was reinstated from the 10-day disabled list after missing 29 games with a right oblique strain. The first game takes place at 1:05 p.m. ET, with the second meeting set for 7:05 p.m. ET.
