AUBURN HILLS — Greg Monroe and Charlie Villanueva returned from injuries Friday night in Detroit’s loss to the Dallas Mavericks.

Monroe had 14 points and 10 rebounds in the loss for his 29th double-double of the season.

Monroe was playing with a sprained ankle that caused him to miss the first game of his career due to injury. He said the ankle is feeling better, but he’s still not 100 percent.

“It’s a little sore,” Monroe said. “I think I did okay. I still got a long way to go. It was giving me a little pain.”

Villanueva missed Wednesday’s game with a sore left hamstring. He didn’t play in the first half Friday, but had 12 points and three rebounds in 14 minutes, including two big 3-pointers.

No Drummond update
When Andre Drummond was first diagnosed with a stress fracture in his back, the timetable for his return was four to six weeks.

It’s now been four weeks, but there is no update as to when Drummond will return.

“I’ll be honest with you, I really can’t answer that question only because I don’t know,” Pistons assistant coach Brian Hill said when asked if he thought it would be close to six weeks now. “I know Andre is doing a lot of stuff with Arnie Kander, our strength and conditioning coach.

“We literally have had no discussion what so ever as to any type of a timetable of when he might be back. I just leave that entirely up to Arnie to say how things are going and when we might see him. But so far we haven’t had that discussion.”

Frank still not with team
Pistons head coach Lawrence Frank remains away from the team as his attends to his ill wife.

There is no indication when he will return as the Pistons prepare to head West for a four-game road trip starting Sunday against the Los Angeles Clippers.

“That’s our head coach, it affects us a whole lot,” Greg Monroe said when asked about not having Frank around. “(The coaching staff) works with him everyday. It’s different not having him here, but at the same time these guys know what he expects. They have worked with him every day for two years now. I’m pretty sure they have dialogue in between games and after practice. It’s tough him not being here, but at the same time I don’t think there’s any drop off with those guys. It’s his staff.”
