Green will not return to Saturday's game against the Wizards due to left calf tightness, Dalton Johnson of NBC Sports Bay Area reports.
Green, who had just returned from a three-game absence Saturday due to an illness and a disc problem, played only three minutes before checking out of the contest and heading to the locker room while sporting a significant limp. He'll finish the contest with zero points (0-1 FG) and one rebound.
