Saturday's performance was an extension from the Jackson's last outing, August 5 at Wrigley Field against the Chicago Cubs, when he threw four scoreless innings after allowing four runs in the first inning of the National's 7-4 loss.
Harper was diagnosed with a hyperextended left knee.
Harper was helped off the field, while putting no weight on his left leg.
As per usual with the Washington Nationals, no injury news is usually given until after the game and its unlikely we will know the full diagnosis until some point during the doubleheader tomorrow.
Severino, 24, returns to the Nationals for his second Major League assignment of the season. The 2015 MVP is hitting.326 with 29 home runs and 87 RBIs in 106 games this season, and his presence in the lineup is crucial to Washington playing deep into October. It's been a long year for the Giants who have been struggling since after the 2016 All Star game and have done so in 2017 and the National League West is not a division to struggle in.
Since Harper made his MLB debut on April 28, 2012, the Nationals have the second-most regular-season wins in baseball (they're 526-397), behind the Los Angeles Dodgers.

The All-Star has been sidelined since leaving his July 23 start at Arizona after two innings. The 15-year veteran had to mentally prepare to pitch again Saturday, and had to wait out an additional three hours because of more rain.
Despite the horrific accident, Harper did manage to walk around the club house following the game.
The Nationals are seeking to avenge their NLDS loss to the Dodgers previous year in a series that went to a decisive fifth game, and a one-run loss when Clayton Kershaw came out of the bullpen to record the final two outs. "He's going to get an MRI", Baker said. Giants manager Bruce Bochy realizes the situation Stratton faced. Washington hopes the same fate doesn't happen to Harper.
Along with being rivals, Baker and Bochy are friends. Of the 13 managers ahead of them, only Gene Mauch is not in the Hall of Fame. The good thing is he's young and strong. In his career, he is 4-4 with a 5.03 ERA in 11 games (10 starts) against the Giants.
It means the Giants will have a late night flight to Miami before their series opener there on Monday.
Virginia was in the news Saturday for the racial unrest that took place. Stratton has taken the spot of Matt Cain in the rotation.
