Shumpert (sprained shoulder) questionable

NEW YORK -- Knicks guard Iman Shumpert suffered a sprained right shoulder in the first quarter of Tuesday’s game against the Celtics and is questionable to return.

Shumpert dealt with shoulder soreness in training camp but has remained relatively healthy throughout the season, playing in every game this season.

If Shumpert were out for an extended period of time, J.R. Smith or Tim Hardaway Jr. would likely replace him in the lineup.

He suffered the injury with 7:55 to play in the first quarter and did not come out for the second quarter.

In other injury news, veteran Knicks forward Kenyon Martin returned after a five-game absence due to a left ankle injury. Martin aggravated the injury against the Pacers on Jan. 16.

“Just overuse,” the 36-year-old Martin said. “Been going every day and playing a lot of minutes. Just needed a break. Not one thing happened. Just been fighting through it, fighting through it, fighting through it, and the body lets you know. So at my age, you got to listen.”

Martin's return didn't last long. He limped off to the locker room late in the second quarter after apparently tweaking his ankle.

Martin has missed eight games this season due to left ankle issues. His minutes early in the season were limited due to soreness in his ankle. He first hurt it last April.
