Pence had a MRI exam Wednesday after he started limping in Game 1 of Tuesday's doubleheader against the Nationals at Citizens Bank Park. The Phillies said Pence has a mild strain of the patellar tendon and is day to day.
He is expected to play sometime this weekend against the Mets in New York.
"I feel good," Pence said. "I never really thought I needed a MRI. Hopefully I'm able to pinch-hit. I'm able to swing. A day [off] here, we'll see [Thursday]. I've had it before. I can play on it. ... I could play today, but we're trying to make the best decision. And we feel like this is best."
It made sense to keep Pence out of Wednesday's lineup with Game 1 of the National League Division Series just 10 days away. Pence sounded confident this is a minor issue and will not carry into the playoffs.
"I'll be fine," he said.
"He's had it for a long time," Phils manager Charlie Manuel said. "He's been playing, but evidently someone thought it was too serious for him to continue and wanted to give him some rest."
