Wolves centre back Gary Bree may miss his sides trip to The Ricoh Arena after having picked up an injury in the win over West Bromwich Albion on Sunday.
Breen was withdrawn as a precautionary measure by manager Mick McCarthy half way through the second half.
'I got the injury early on in the first-half,' he told the clubs official site.
'It got progressively worse as the game wore on and with Jody on the bench we felt it best not to take any chances.
'It feels a lot better this morning and, hopefully, I'll be OK for tomorrow's game at Coventry.'
With captain Jody Craddock stepping into the breach so ably, Mick McCarthy may not be losing too much sleep over Breen's fitness and will almost certainly choose to rest him if he is anything short of 100% fitness
