The Bulls will have a new look when they return from All-Star Weekend

The look will be different when the Bulls take the court Thursday against Philadelphia.

Vice president of basketball operations John Paxson said change was coming at the trade deadline, and coach Fred Hoiberg reiterated it leading up to this weekend’s All-Star festivities.

Minutes for veterans?

Reduced.

The players usually at the end of the bench waving towels?

Get familiar with them.

Call it either audition time or one last effort to get the tank back on track, but with just 25 games remaining for the Bulls, the front office wants to see exactly what it has moving forward.

“I think everybody has been pretty clear that once we get back from the break that guys are going to get chances, get opportunities, and we’re still trying to figure out how to go about that,’’ Hoiberg said.

It’s those details that remain a mystery.

Justin Holiday leads the team in minutes per game at 34.1, while Robin Lopez was fourth at 27.7. With Kris Dunn back from the concussion protocol and Zach LaVine stretched out to almost 33 minutes if need be, they will join rookie Lauri Markkanen (30.3 minutes) in the starting lineup.

There has been no indication that the starting five will change for now.

LaVine, Dunn and Markkanen finally will get a long stretch of games to play together — something injuries and rehabilitation stints have prevented — leaving both Lopez and Holiday with much shorter work nights.

“I realize my role here, you know,’’ Lopez said last week, when asked about the pending cut in minutes. “There’s things to be done on the floor as well as off the floor, and if that’s part of my off-the-floor duties, so be it. I’m up for that.

“I’ve always told you guys I’m a team guy.’’

Both Lopez and Holiday could be attractive trade assets this summer, considering both have expiring contracts after the 2018-19 season.

What Hoiberg and Paxson want to find out is what other pieces they can feel good about moving forward.

Bobby Portis and Denzel Valentine are no-brainer rotation guys who mesh well with the current makeup of the team.

The Bulls also have two potential first-round picks in the June draft, so that gives the Bulls seven young players as part of their foundation.

It also leaves some serious questions to be answered.

— Can Cameron Payne be a back-up point guard?

— Will the real Paul Zipser stand up?

— Did they make a mistake extending Cristiano Felicio?

— Does David Nwaba have staying power as a defensive specialist?

— What does Noah Vonleh have left, if anything at all?

The nice thing is all five seemingly will get the opportunity to answer those questions with extended playing time.

“Noah is one of those guys that we do want to take a look at, and see what he is,’’ Hoiberg said. “Not only Noah, but Cristiano. Zipser has been playing better. And then obviously Cam as well at some point. We’ll put some things together over the All-Star break as far as a plan on how we’re going to implement all these guys coming back, but we’re excited to see how they’ll do.’’
