Dylan Harper suffered a calf injury during the San Antonio Spurs' 130-118 loss to the Phoenix Suns on Sunday.

Harper was injured in the second quarter and did not return to the game.

The rookie left the arena in a walking boot while using crutches.

"I believe it's something with this calf, but I don't have anything as of yet," said Spurs coach Mitch Johnson after the game.

Harper is averaging 14.4 points and 4.6 rebounds on the season.
