Jose Calderon may be done for year after Achilles complication

Jose Calderon expressed major doubt he’ll be back this season after once vowing to return from a strained Achilles.

Calderon, who first injured the tendon in Boston on Feb. 25, missed his 16th straight game Friday against Boston, as the Knicks fell 96-92. Calderon underwent a platelet-rich plasma, blood-spinning procedure Monday because the strain wasn’t healing.

“We got to be honest with this — it’s not a lot of chances,’’ Calderon said. “After the boot is off, we’ll have to make another decision.’’
