The New York Yankees don't know how long Jacoby Ellsbury will be out of the lineup, but it has been determined that the outfielder won't require surgery on his right knee.

Ellsbury will be examined by Chris Ahmad, New York's team doctor, when the Yankees return home on Friday.

"It is not anything that requires surgery so we are not holding anything that is doom or gloom," Joe Girardi said. "We just have to see how he responds over the next few days and see what Dr. Ahmad says."

An MRI on Ellsbury's knee was negative.
