There was a lot of talk coming from the Bulls’ locker room in the last 24 hours about a ‘‘next-man-up mentality.’’ On Wednesday, coach Billy Donovan showed whom those next men up would be.

With guards Coby White (strained right calf) and Josh Giddey (strained left hamstring) and center Zach Collins (sprained right toe) out for at least a week or two, Donovan unveiled his new-look rotation — at least for now.

Donovan tried to match a physical Pelicans lineup with size, starting forwards Isaac Okoro, Matas Buzelis and Jalen Smith and center Nikola Vucevic and going only with Tre Jones at guard.

Donovan’s first five off the bench were forward Patrick Williams, swingman Dalen Terry and guards Jevon Carter, Kevin Huerter and Ayo Dosunmu.

Expect it to be a work in progress and one that might change from game-to-game, based on matchups and who is playing well.

‘‘Everyone knows their role on this team,’’ Okoro said. ‘‘No one is too big-headed or out there trying to be a superstar. Everyone knows their roles, knows what they need to do to impact winning. So as long as guys know that, I think we’ll be in a good place.

‘‘We have enough here. Just play with energy, play with a high spirit, do the things we can control. Of course, not having bodies out there is bad, but we have enough. Control what we can control.’’

That’s the same message Donovan has been preaching since Monday, when he talked about Collins’ injury before White and Giddey were hurt against the Timberwolves.

‘‘It’s a results-oriented business, but I look at it as a 48-minute game,’’ Donovan said. ‘‘Can we play to an identity covering for each other on defense, helping each other on offense, moving the basketball, playing the right way, not turning it over? To me, there are certain things we can do as a basketball team. Are we good enough to actually overcome and go win games? It remains to be seen. But I know if we don’t do those things, we have no chance.’’

Back-to-back talk

The games against the 76ers and Bucks on Friday and Saturday represented the first back-to-back White had played in this season.

White had suffered a strained right calf in August and missed months because of it, so the Bulls had stayed away from giving him that kind of workload. He came out of the back-to-back feeling fine but then felt tightness in the next game.

That’s why Donovan and the Bulls’ medical staff might shut him down from back-to-backs for the rest of the season when he is healthy again.

‘‘That’s been a topic of conversation,’’ Donovan said. ‘‘That was the first back-to-back he played. He came out of it fine, but they are trying to go through every minute detail that he does every single day.’’

Just whispers

The Sun-Times and other media outlets have reported the Bulls are keeping an eye on the situation with Zion Williamson, the No. 1 overall pick in 2019, and his future with the Pelicans. They can look away for the time being, however, because he seems to be in a good place with his team.

Not only is the injury-prone Williamson coming off a December in which his availability was solid — he played in nine games since Dec. 14 — but so were his numbers. He averaged 22.5 points on 60.2% shooting from the field.
