Tim Duncan tweaked his left knee in San Antonio's win over Golden State on Monday night.
The sight of Duncan laying on the floor, clutching his knee was a scary one for the Spurs.
"Bad, bad memories," Tony Parker said. "I thought something was seriously wrong with his knee."
It turned out to be fine as Duncan returned without a problem in the second half.
He finished with 16 points and seven rebounds in the 113-102 win.
