Heat forward Derrick Jones Jr. helped off court with apparent serious knee injury

Heat forward Derrick Jones Jr. suffered an apparent serious knee injury against the Knicks on Sunday.

The 21-year-old landed awkwardly on his leg and collapsed to the court after being fouled on a drive to the basket. He remained down for several moments before being helped off the floor.

Jones tallied one rebound in four minutes of action before exiting the game. He was not eligible to return because he did not shoot the free throws after the play.

The forward underwent X-rays, which came back negative, the team announced. 

Jones entered the game averaging 7.6 points and 4.5 rebounds in 18.4 minutes per game this season. He was shooting 51 percent from the field and 36.5 percent from the 3-point line.

The Heat came into the matchup Sunday in seventh place of the Eastern Conference standings with a 23-24 record.
