Hull manager Steve Bruce has hinted he will shuffle his pack to cope with the physical presence of Blackburn at Ewood Park.
The Tigers boss enjoyed a winning start in his first npower Championship match in charge, as they beat Brighton 1-0 thanks to a goal from substitute Jay Simpson.
The performance of Simpson and the other replacements, coupled with a lack of match-fitness for a number of his players, has given Bruce food for thought ahead of their clash with Rovers.
Forward Matty Fryatt (Achilles) remains Hull's only injury absentee, but Corry Evans, Paul McShane and Alex Bruce will be hoping to force their way into the manager's thoughts.
"In terms of Wednesday, I think we will need to change slightly in terms of personnel," Bruce told Hull's official website.
"Going to Blackburn on a Wednesday night, we need to be physically ready for the challenge that they're going to throw at us."
