Ireland's John Lacey will referee his first ever RBS 6 Nations match in February, while Alain Rolland is also included in the Elite Panel in what is his last season.
Kick-off 2.30pm unless stated -
Belfast Harlequins (6th) v De La Salle Palmerston (2nd), Deramore Park
Another week, another big game for both teams. Neither club can afford to lose at this stage and with only three points between them and promotion at stake, this will be a big game at Deramore Park.
Neighbours and now rivals. All square on 27 points. Possible promotion and play-off places at stake. The voiceover would not do it justice.
To add to the occasion you can also follow the game on twitter with score updates direct from the 'Brook as Old Wesley and mobile technology partner Eircom Mobile Broadband will keep you up to date on www.twitter.com/OldWesleyRFC
Concentrate on the job in hand. That will be the message in the Bruff dressing room on Saturday. But there will surely be one eye on Donnybrook to see what advantage they can take.
Bruff are level on points with the Bective and Wesley and could move right up the table should results go their way.
Highfield will not be an easy target. They are only five points adrift of the 'College lads but they badly need a win to keep them out of the relegation zone.
Were Old Crescent or Clonakilty to win, they could leapfrog the Cork side - pushing them to third from bottom.
