The Denver Nuggets took the floor for Wednesday morning’s shootaround at the Toyota Center without Paul Millsap, who had returned to Denver to seek more medical care on his injured left wrist.

Teammates and coaches acknowledged they already miss Millsap, the Nuggets’ four-time all-star, second-leading scorer and crucial veteran presence. But now they have no choice but to move forward, both immediately in preparing for Wednesday night’s game against the Western Conference-leading Rockets and for the foreseeable future.

“That injury is not going to define us or our season,” coach Michael Malone said. “We’re going to continue to prepare, to work, to fight and to compete. One man goes down, you have to have guys step up.

“The great thing about having a deep roster and a very deep frontcourt is other guys are ready to take advantage of those minutes.”

After originally diagnosing Millsap’s injury — which occurred during Sunday night’s loss at the Los Angeles Lakers — as a sprain, the team officially specified Wednesday that a ligament was affected. Malone said Millsap met with team doctors Tuesday and would “get some other opinions before we make a decision as to what the best course of action is.” A league source confirmed to The Denver Post Tuesday night, however, that Millsap will have surgery and could miss up to three months.

After Kenneth Faried started Monday’s win at Sacramento, Malone started Wilson Chandler (who returned from a back injury) at power forward and Will Barton at small forward against the Rockets. Malone said that starting job, as well as the rest of the big-man rotation, will be determined from game to game for now. Malone said he’s been pleased with the play of Trey Lyles, who totaled eight points and six rebounds in 19 minutes against the Kings. Mason Plumlee is also an option when the Nuggets want to deploy a bigger lineup, while Juancho Hernangomez can play that spot when Denver goes small.
