The Yankees will be without Jacoby Ellsbury for at least two weeks.

The 31-year old outfielder sprained a ligament in his knee after getting his spike caught in the dirt while swinging at a pitch during Tuesday's game in Washington, Yankees.com reports:

"They literally haven't told me anything," Ellsbury said. "They put me in a brace, and I've just been doing treatment all day. I'll be on the plane tonight, off-day tomorrow, go in and do treatment again, and Friday see the team doctor."

Ellsbury has hit .324 and scored 29 runs in 37 games with the Yankees this season.
