The Celtics and rookie J.R. Giddens have agreed on a two-year deal with an option for another two years.
Giddens, selected 30th in this year’s draft, averaged 16.3 points and 8.8 rebounds in his senior year at New Mexico. He could play spot minutes but shouldn’t be much help in fantasy leagues. The Celtics’ second-round pick, guard Bill Walker, remains unsigned.
