The Nationals will determine Bryce Harper’s status for Monday’s series opener in San Francisco tomorrow afternoon, Manager Davey Johnson said. Harper missed the past two games with swelling in his left leg, the most prominent lingering effect from Harper’s collision last Monday with the right field wall in Dodger Stadium.

“It’s a tough situation with Harp out,” Johnson said. “He’s getting better. He should be maybe okay for tomorrow.”

Harper has been receiving extensive treatment on his knee. Multiple teammates noted Harper has been hurting, and that even missing one game for him would require a significant physical issue.

“We just need to get everyone healthy,” third baseman Ryan Zimmerman said. “I don’t know if Bryce is going to be able to play or what’s going on with that.”

Harper, who said Saturday he expected to miss two games, offered what could be a promising hint on his Twitter account. He wrote: “San Fran is one of my favorite places to play! Such an incredible ballpark and fan base! Ready to play there again!”
