The Celtic League fixture beteween Llanelli Scarlets and the Ospreys at Stradey Park has been postponed due to a frozen pitch.
A bumper 11,000 crowd had turned up to see the local derby between the mid-table Scarlets and injury-ravaged Ospreys, but were left disappointed as parts of the playing surface were deemed unsafe on account of the hard ground.
The postponement means the Scarlets remain seventh in the Celtic League table, while the Ospreys languish third from bottom, although both sides have games in hand.
