Hull City forward Liam Miller is facing up to six weeks out with a hamstring injury.
Head coach Sergej Jakirovic confirmed that the Canada international could be out until December after sustaining the injury in last weekend's home draw with Charlton Athletic.
The news is a blow given Miller is only five games into a return following 11 months out with a anterior cruciate ligament injury.
"At least we have two weeks international break, which is good for us, but it is huge in terms of the impact to our team and it is very frustrating for him," Jakirovic told BBC Radio Humberside.
