Richie Power looks likely to miss Kilkenny's opening championship game against Wexford on Sunday as he struggles to overcome a knee injury.
There are concerns that Power may also miss the Leinster final, should Kilkenny advance that far, or a second-round qualifier in early July.
Power has been limited to club activity since last year's All-Ireland final replay when he turned the screw on Tipperary with an impressive display.
The Carrickshock ace sustained knee ligament damage in last year's drawn Leinster semi-final against Galway, forcing him out for almost two months, and his return provided a big lift for the Cats in the All-Ireland final.
Kilkenny are expected to have everyone else available as they launch the defence of their Leinster title.
TJ Reid has overcome a shoulder injury while Michael Fennelly has shaken off his latest back injury that continues to plague him. He returned to training last week.
Fennelly missed the Leinster semi-finals against Galway and the final against Dublin due to a similar injury last summer.
Michael Rice is also available having missed last season with a cruciate injury. He played in a challenge against Limerick and has also taken part in club games as part of his rehabilitation.
Captain Joey Holden is expected to take over as full-back from JJ Delaney when the team is announced.
Meanwhile, Monaghan have suffered a major blow with reports that full-back Drew Wylie is out for the season with a suspected cruciate injury.
