Callum Wilson, Allan Saint-Maximin and Ryan Fraser were all added to Toon’s lengthy absentee list after Monday’s draw against Manchester United.
Eddie Howe’s side were down to the bare bones before Monday and could only name eight subs – two of whom were goalkeepers.
Ciaran Clark, Matt Ritchie, Joe Willock and Karl Darlow were all missing, joining Paul Dummett, Jamal Lewis and Federico Fernandez on the sidelines.
Wilson then pulled up just before half-time and is set to be out for months with a feared torn calf.
Saint-Maximin limped off just before the end with a less serious calf issue while Ryan Fraser picked up a hamstring injury.
Fabian Schar was also seen hobbling at the end and Javier Manquillo is suspended for the game at Goodison Park.
That leaves 11 fit senior outfield players, keeper Martin Dubravka and youngster Elliot Anderson, who was on the bench and has played one Prem game.
Fellow teen Joe White was also a replacement but is yet to play for the first team.
After the 1-1 draw with the Red Devils, Howe said: “It’s 13 plus a goalkeeper to have enough players for a game. We’re going to be dangerously close to that number.”
