Sunderland defender Tom Beadling has been training with the first-team squad for the past 10 days, according to the Sunderland Echo.
Beading has been called up to the senior squad due to the lack of centre-backs current available to Dick Advocaat and he could even have a chance of being on the substitutes' bench against Newcastle United this weekend.
With Wes Brown sidelined, Sunderland have had just one fully fit centre-back available to them on the training ground this week, due to international call-ups, and Beading has benefitted.
The 19-year-old is regarded as one of the Black Cats' finest prospects, and was handed a new contract to recognise this earlier in the season.
Since then Beading has continued to be one of the side's top performers in their development squad, but he is yet to be handed a chance in the first-team.
He will have been hoping to prove to Advocaat that he has the ability to play for their senior squad this week, though, having been given a chance to train with Sunderland's high-profile stars.
Beading was not the only Sunderland youngster in first-team training this week, with Duncan Watmore also involved.
