Leinster have confirmed that Jordan Larmour will require further assessment before a call is made on his fitness for this weekend's Guinness Pro14 final against Ulster.
Larmour failed a HIA in Friday's victory over Munster at the Aviva Stadium after being caught accidentally by the stray knee of JJ Hanrahan after 46 minutes.
He is following the IRFU's return to play protocols, which would allow him to play again after seven days - Saturday's final takes place on the eighth day after their semi-final win.
There was better news for James Ryan, who is available for selection following shoulder surgery over the summer. The second row was given a 10-12 weeks recovery time by the province at the start of last month, so his return is a surprise.
Meanwhile, Tadhg Furlong and Dan Leavy will be looked at before a decision is made on their inclusion in the squad for the Ulster clash, while Fergus McFadden is increasing his training amount but won't be available.
Leinster are going for a third Pro14 title in a row on Saturday.
