Brooklyn Nets interim coach P.J. Carlesimo says he has “no clue” if he needs to advance past the first round of the playoffs to keep his job.

“There’s nothing we can do about that,” Carlesimo said Tuesday on ESPN New York 98.7 FM’s “The Michael Kay Show.”

“We’re trying to win the series and get to Miami ... I can’t control that.”

Carlesimo reiterated that it’s not something he thinks about -- except when it’s brought up to him in interviews.

• Joe Johnson has gutted through the playoffs so far despite dealing with a plantar fasciitis ailment in his left foot.

“I don’t think he’s getting better, but Joe’s gonna play,” Carlesimo said.

Chicago Bulls center Joakim Noah is dealing with the same injury.

“Neither of them are gonna be healthy the rest of this year, they’re just playing through it,” Carlesimo said.

“Joe Johnson is a warrior, he’s doing great things considering the condition his foot is in.”

• Carlesimo said of Gerald Wallace, “We’re not going anywhere without Gerald Wallace. ... He doesn’t have to score to play minutes for us.”

• The NBA rescinded C.J. Watson’s technical foul he picked up in the second quarter of Game 4.
