Triano said backup center Alex Len will miss Wednesday's game against the Pacers with an Achilles' heel "flare-up."
Greg Monroe will back up starting center Tyson Chandler.
"It's been bothering him a little bit, just the wear and tear on it," Triano said. "I think the day will give him rest and he'll be able to bounce back and play at home."
Chandler's flagrant foul
Chandler was whistled for a flagrant 1 foul on Denver's Mason Plumlee in the final minute of the first half of the Suns-Nuggets game on Friday, but the the NBA Wednesday upgraded the call to a flagrant 2.
