Tony Parker posted on his Facebook account Wednesday that he has a slight hamstring “stretch,” seemingly putting his availability for Thursday’s Game 4 in question. Parker’s message, as translated via Google: “I just had MRI. Result: I suffer from a slight stretch to the hamstring. We’ll see tomorrow how I feel, I really hope to play!” The Spurs have yet to release an official status report. More details to come when available. Parker, who was stuck in traffic and missed warmups for the Spurs’ 113-77 victory in Game 3, was injured at some point in the third quarter.
