THE 2011-12 British & Irish Cup will kick off with a clash of previous winners when Bristol Rugby travel to Cornish Pirates.

Bristol, who beat Bedford Blues 17-14 in last month’s final, will face inaugural 2010 holders at the Mennaye Field on Wednesday, September 21.

“Winning the British & Irish Cup last season was a major boost to the club after a challenging campaign,” said Bristol Rugby Head Coach Liam Middleton.

“We’ll be looking to defend the trophy this time round, although we expect tough opposition from Cornish Pirates, Moseley, Neath and Ayr. All four games will be fierce encounters and it should be a really exciting competition.”

With all English ties played in midweek to ease potential weekend fixture congestion, RFU Championship newcomers London Scottish start with the most local of derbies against London Welsh.

The third British & Irish Cup will see a change in format, with a cross-pool fixture list which guarantees two home fixtures for each side.
