Three days after he severely injured his hamstring, the Nationals have yet to declare how long Ryan Zimmerman will be out this season. Manager Matt Williams indicated on Friday that Zimmerman was resting for an initial period of two weeks and added that the team didn’t have a grade of the strain yet.

On Saturday, General Manager Mike Rizzo said the Nationals would check on Zimmerman when the team returns from their current roadtrip, which ends Wednesday in Miami.

“He’s with our [physical therapist] and he’s doing physical therapy at home right now,” Rizzo said. “We’ll check in when we get back from the roadtrip.”

Rizzo declined to say yet how long Zimmerman would be out. Zimmerman has been expected to receive further evaluation on his hamstring early next week by the team’s doctor.

“Eventually he will,” Rizzo said. “He’s been diagnosed. He’s got his calendar. Right now, he’s just got PT and we’ll re-address when we’re at home.”

Although the Nationals have yet to give specifics about the severity of Zimmerman’s strain, Zimmerman and the Nationals have admitted that it is a significant one. Fellow National Wilson Ramos suffered a grade 1 hamstring strain earlier this season and he returned after two weeks, despite the fact that hamstring injuries have been a recurring problem for him.

Santiago Casilla of the Giants suffered a grade 2 strain and missed four weeks, while Corey Hart of the Mariners had the same grade injury and he missed nearly seven weeks. Recovery from a grade 3 strain, the most severe, can take as long as three to six months.

How long Zimmerman will be out could affect the Nationals’ plans in the trade market. The deadline is Thursday and, if Zimmerman is expected to miss much of the rest of the regular season, perhaps the Nationals would be more inclined to pursue an infielder.
