The return to competitive action for Munster and Irish prop, Marcus Horan, failed to materialise on Saturday.
Horan was to have played some part in Shannon's Munster Cup semi-final against UCC, but the pitch at Tom Clifford Park was unplayable.
Horan has not played since he retired during Munster's Heineken Cup tie against Benetton Treviso on October 17 and was subsequently found to be suffering from a minor heart ailment.
Horan is back in full training, but lacks game time and a choice will have to be made by Munster coach Tony McGahan whether he will afford Horan game time when Munster host the Scarlets in Cork next Sunday (5pm).
Alternatively Horan could be chosen for Shannon who travel to play table toppers St Mary's College in the AIL next Saturday, which is a vital game for the club side.
Next weekend is the last opportunity for Horan to get game time as Munster travel to face Benetton Treviso in the Heineken Cup a week later.
Irish coach Declan Kidney will also be anxious for the 66 times capped Horan to see competitive action ahead of the defence of the Grand Slam championship which starts against Italy on February 6.
