John Carver and Steve Stone are set to be in charge for Newcastle's next two matches with Alan Pardew poised to become Crystal Palace's new manager.
Pardew did not take training on Tuesday and assistant manager Carver and first team coach Stone have stepped in.
They will oversee Thursday's Premier League home game against Burnley and Saturday's FA Cup tie at Leicester.
Pardew is set to leave the Magpies, who are ninth, for 18th-placed Palace.
"Crystal Palace have offered compensation at a level whereby Alan has now been permitted to speak to them," said a Newcastle statement on Monday night.
Pardew, 53, has been Newcastle manager since December 2010 and is currently the fourth longest-serving manager in English football, after Arsenal's Arsene Wenger, Exeter City's Paul Tisdale and Karl Robinson of MK Dons.

|"I think Alan's done a great job at Newcastle after being there four years. I think they're in a better position than they've ever been and they've played in Europe, he got Manager of the Year and recently Manager of the Month.|
|"I worked for him for three years and he's the best coach I've worked with. He's hands on. He doesn't sit back and let things happen. He comes up with the procedures and does the coaching himself."|
The former Reading, West Ham, Southampton and Charlton boss steered Newcastle to a fifth-placed finish in the Premier League in 2012 and is under contract at St James' Park until 2020.
Supporters on Tyneside called for Pardew to be sacked earlier this season when Newcastle were in the bottom three at the start of October.
He has strong links with Palace having spent four years playing in their midfield from 1987, and scoring the winning goal as the Eagles beat Liverpool 4-3 after extra-time in a 1990 FA Cup semi-final and played.

|"Since the debacle of Kevin Keegan and then Alan Shearer's spells in charge at St James's Park, owner Mike Ashley has gone with those he either knows or trusts."Chris Hughton, Pardew, Joe Kinnear and managing director Lee Charnley were all either working for the club and promoted or had a pre-existing relationship with the Sports Direct billionaire."Doing things a different way has been a hallmark of Ashley's time in control on Tyneside. His decision over Pardew's replacement could yet be another example of his determination to conduct business on his own terms."|
