Central defender Bikey and midfielder McEachran both suffered ankle injuries during the 1-0 npower Championship victory over Blackburn and will be assessed over the next 48 hours.
Defender Seb Hines and midfielder Faris Haroun also missed the Rovers game, both with hamstring problems, and they will also face late checks.
Long-term absentee Rhys Williams played the second half of the Boxing Day match after recovering from ankle ligament damage, his first senior appearance in four months, and manager Tony Mowbray will hope he suffers no ill-effects.
Midfielders Julio Arca (toe) and Muzzy Carayol and striker Curtis Main (both knee) are continuing to work their way back to full fitness.
