Ramos said he is out for the rest of the season and hopes to have surgery in two to three weeks, once the swelling in his knee goes down.
The last seven months have not been kind to Ramos. Last November, Ramos was kidnapped in his native Venezuela. Ramos, who was playing for Tigres de Aragua in Venezuela's winter league, was taken from his home in Santa Ines by four armed gunmen.
On Saturday, Ramos suffered the knee injury in the seventh inning as he chased after a ball that had ricocheted off his glove on a pitch from Jordan Zimmermann.
"It was very, very bad for me. I feel down," Ramos said. "I will have a good rehab. After that, I'm going to come back and play. ... I will not come back for this season, but I will be good for next season."
Ramos plans to recover in the D.C. area and hopes to have his parents take care of him. He said he does not want to go back to Venezuela to recover from his knee injury.
Ramos wasn't the only catcher on the Nationals who suffered an injury. Two days after Ramos went down, Sandy Leon sustained a high right ankle sprain and was placed on the 15-day DL.
The Padres had runners on second and third with one out, when Orlando Hudson singled to center field. Yonder Alonso scored easily, but Chase Headley barreled into Leon and scored the third run of the game for San Diego.
"I felt bad for him," Ramos said about Leon.
