Since the Giants don't come back to D.C. this year, it was Major League Baseball's call on whether or not this game should be played.
Giants manager Bruce Bochy said, "I don't know what happened really. He's going to get an MRI", Baker said.
There has been no update on Harper's injury.
On Saturday, he consistently shut down Cubs threats while scattering five hits in 6 2/3 scoreless innings.

Secretary of State Rex Tillerson asked Kurdistan Regional Government President Massoud Barzani to postpone the referendum. They are effectively running the region, also claimed by Turkmen and Arabs.
Should Strickland and Harper face off this weekend, it's unlikely that any fireworks would take place.
Bochy was set to give catcher Buster Posey a rare day off Friday and said he would keep him out of the lineup Saturday.
Harper was hurt about 20 minutes after the first pitch, which came three hours later than planned because of a storm that hit Nationals Park in the evening.
Harper suffered a hyper-extended knee, according to Washington manager Dusty Baker.

Brandon Drury's two-run double keyed a four-run sixth inning that broke up Jon Lester's pitching duel with Patrick Corbin, and Arizona ended a three-game losing streak by beating Chicago.
Giants players were already in street clothes talking to family and friends and walking toward the team buses before the game was announced as postponed. Harper, the 2015 MVP who is hitting.326 with 29 home runs and 87 RBIs as the most fearsome hitter in the league this season, did not speak to reporters after the game.
"When talking about building an organization, you'd be short-sighted you'd be short-sighted to think about the 25 men on the major league roster", Rizzo said. Baker said Bochy was the first one to call him when he was sacked by Cincinnati, and Baker called in April when Bochy had a heart procedure. The good thing is he's young and strong.
