The back end of the Knicks frontcourt could be shorthanded for their pivotal Game 6 matchup against the Celtics on Friday night. The team announced reserve center Precious Achiwua as a new add to the team’s injury report, listing him as questionable for Friday’s showdown at Madison Square Garden due to a sprained ankle.

Precious Achiuwa’s ankle injury casts doubt on his availability for Game 6, just as the New York Knicks prepare for their biggest playoff moment in over two decades.

The New York Knicks are on the road on Wednesday night as they take on the Boston Celtics in Game 5 of their second-round series. New York enters Wednesday’s game just a victory away from advancing to the Eastern Conference Finals after they were able to take a commanding 3-1 series lead with their victory in Game 4 on Monday at home.
