If Shelvey features, he will become the youngest player to ever wear the red shirt, at the age of 16 years and 52 days, beating the record set by Paul Konchesky in 1997.
Addicks boss Alan Pardew has said that one of the two scholars have a great chance of being in the 16 for the trip to Loftus Road, and it looks more likely to be Under 18 captain Wagstaff, who has been in the first team squad before this season.
In goal, Nicky Weaver returns from suspension in place of Darren Randolph.
Darren Ambrose may start in an attacking central midfield role, with Zheng Zhi and Lee Cook providing the width.
And after finally breaking his Addicks duck in the draw with Southampton last Saturday, Andy Gray will start upfront alongside Leroy Lita.
Possible side for QPR: Weaver, Halford, McCarthy, Bougherra, Thatcher, Zheng, Ambrose, Holland(c), Cook, Gray, Lita
Subs: Randolph, Wagstaff, Semedo, Varney, Iwelumo
