Kilkenny pair Henry Shefflin and Brian Hogan are facing a race against time to be fit for the All-Ireland SFC final next month, after both picked up injuries in the first half of Sunday's overwhelming win over Cork.
Centre-back Hogan damaged a shoulder after just 15 minutes, and centre-forward Shefflin fell heavily on a knee eight minutes later.
"It's a worry all right. Neither of those players would go off easily. We're hoping things aren't as bad as they seemed, but things have to be assessed obviously over the next couple of days," said manager Brian Cody.
"They're serious players and it's only a few weeks until the All-Ireland, so we'll be doing everything we can to make sure they are fit. Brian has hurt his shoulder and Henry has hurt his knee, but that's the only information that we have at the moment."
