The 20-year-old Londoner has impressed in Liverpool's sluggish early season displays and was initially called up for the European Under-21 Championship play-off with Serbia by Stuart Pearce.
However, Shelvey is suspended for the first leg of that game at Norwich, and Hodgson has taken the opportunity to bring him into the senior fold.
With Frank Lampard, Michael Carrick, James Milner and Tom Cleverley all capable of playing in central midfield, Hodgson does have options, even though skipper Steven Gerrard is himself suspended for Friday's game with San Marino.
It has therefore been suggested Shelvey's presence at St George's Park is purely to further his experience.
There is also a chance he could go back to the Under-21s for the second leg of the Serbia game next Tuesday, although a decision on that will not be taken until the weekend.
