Tanner Glass, a winger for the New York Rangers, has been diagnosed with the disease, which has affected several other teams in the NHL. The Rangers, which reportedly will receive booster vaccinations, share a practice facility with the Knicks.
The Post said that the Knicks' medical staff is on high alert and that the team is "looking to take all precautions."
Knicks guard J.R. Smith is being held away from the team after he missed the Knicks' loss to the Nets on Wednesday with flu-like symptoms and played only six minutes in Sunday's loss to the Miami Heat.
The report says that the team has "all but ruled out" the possibility that Smith has contracted the mumps.
Over 17 games this season, Smith is averaging 9.2 points and 3.4 assists while shooting 39.7 percent from the field. The Knicks (4-15) host the Cleveland Cavaliers on Thursday.
