Newcastle United boss Eddie Howe called up a host of Under-23 players to training at Benton in the build-up to the clash with Leeds United - including Santiago Munoz and Rodrigo Vilca.
The Mexican striker, on loan from Santos Laguna for another 12 months, trained at the senior end of the club's training centre while Vilca, back from a loan spell at Doncaster Rovers, was also handed a chance to impress.
Newcastle have also recalled winger Tom Allan from Greenock Morton after a dozen appearances north of the border and the 22-year-old also trained with the first-team.
