The Celtics landed in Atlanta early this morning for the back end of their fifth back-to-back swing of the season, and Kelly Olynyk has no idea if he’ll be available.

The Celtics rookie sprained his right ankle in the second quarter of last night’s 97-82 loss to Indiana, and is now a day-to-day proposition.

“Everyone who’s played the game of basketball has sprained their ankle,” said Olynyk. “Some of them are lighter, some of them are intense. I wouldn’t say this is intense, intense, where you’re going to be out a month. Hopefully there’s no damage done.”

Olynyk was replaced by Kris Humphries, and the former Net is likely to see increased time tonight.

However, there’s no doubting the loss if Olynyk sits this one out. “That hurt us tonight,” said Celts coach Brad Stevens. “That definitely hurt us.”
