Ulster Bank League: Division 2A Previews - Belfast Harlequins vs Blackrock College

Belfast Harlequins (10th) v Blackrock College (6th), Deramore Park

Bottom side Belfast Harlequins are not mathematically out of it but they have 12 points to make up on Corinthians and a considerably worse scoring difference than the Galway men.

Their defence has really let them down at crucial stages in games, leaking five tries to Banbridge last week and their October meeting with Blackrock, this week's visitors, ended in a 34-3 reversal.

Blackrock's scrum was outmuscled by the Cashel eight in round 14, the 23-14 defeat leaving 'Rock with a huge task to claw their way back into the top four. It is still achievable but they are entering bonus point win-or-bust territory.
