Stoke City pair Ryan Shotton and Brek Shea are being made available.
The Sentinel says Shotton is keen to play in the Championship on a regular basis, but may have to consider a pay cut to make any move there permanent.
Shea is more likely to go out on loan as he seeks the kind of playing time denied him since signing for Stoke in January 2013.
Last season he struggled for confidence during a loan spell at then Championship side Barnsley which ended prematurely.
