The trade between the Houston Rockets and Detroit Pistons may be voided to the back issues of Donatas Motiejunas.

The Rockets sent Motiejunas and Marcus Thornton to the Pistons on Thursday for a protected 2016 first-round pick.

Motiejunas hasn't played since Dec. 31st as he recovers from a sore back.

The Pistons asked the NBA for an additional 24 hours of the 72-hour trade window to determine if Motiejunas can play for them.

"We'll see. If they don't give us more time, we'd have to make a decision," Pistons coach Stan Van Gundy told reporters Sunday, according to the Detroit News.
