The Miami Heat signed former Knicks center Josh Harrellson on Monday, giving the team another developmental center to compete for a roster spot.

Harrellson, 6-10 and 275 pounds, impressed the Heat in a week of workouts recently.

Harrellson averaged 4.4 points, 3.9 rebounds and 14.6 minutes in 37 games for the Knicks last season, including four starts. Harrellson, whose season was interrupted by wrist surgery, made 20 of 59 three-pointers.

Drafted 45th overall by New Orleans in 2011, Harrelson was immediately traded to the Knicks. New York dealt him to Houston last month as part of the Marcus Camby trade. But the Rockets released him last week.
