As the uncertainty surrounding New York Knicks’ forward Rasheed Wallace’s left foot injury lingers, members of the Knicks organization fear Wallace will be out for an extended period, possibly for the entire season, two league sources told ESPNNewYork.com.

Wallace has been out since Dec. 15 with a stress reaction in his left foot.

Knicks coach Mike Woodson said last week that he hoped Wallace would begin running this week, but he told reporters in London on Wednesday that Wallace, 38, has yet to do so.

When asked Wednesday about returning to the court, Wallace said, “It’s not my call.”

One source said Wallace is having trouble pushing off on his left foot.

“It’s not looking good,” the source said.
