The Knicks signed forward Henry Ellenson to a 10-day contract on Tuesday, according to Shams Charania of The Athletic.
Ellenson, 22, was the 18th overall pick in the 2016 NBA Draft by the Detroit Pistons.
He was released before the trade deadline, appearing in just two games this season. The 6-foot-11 forward out of Marquette averaged 3.8 points and 2.2 rebounds in 59 games with Detroit.
The Knicks signed another former first-round draft pick, John Jenkins, to a 10-day contract on Feb. 10 so Ellenson is likely to replace him.
