Clare could be without defender Patrick O'Connor for the rest of the season after he suffered a suspected cruciate ligament injury in a challenge match.
The 2013 All-Ireland winner sustained the injury in a challenge match against Limerick late last week and is set to undergo a scan this week to determine the extent of the damage.
The 30-year-old, who captained the side in the 2017 and 2018 Munster SHC finals, is a key figure in the Banner panel and his absence would come as a major blow to manager Brian Lohan.
Clare take on Dublin in round four of the Allianz Hurling Leagues Div 1 Group B at Parnell Park this Saturday (LIVE on eir sport 1 from 4.45pm).
