Connacht victory stands despite controversy over their late winner
Connacht 20 Wasps 18
Tournament organisers have said that Connacht should not have been awarded the late line-out from which they scored their winning try - through Naulia Dawai - against Wasps at the Sportsground.
The reigning Guinness PRO12 champions struck in the dying seconds, claiming a 20-18 pool victory that keeps them in quarter-final contention.
European Professional Club Rugby also said that the result stands.
In a statement, EPCR said: "The assistant referee, who had taken over as match referee following an injury to Jerome Garces, awarded a penalty to Connacht after time had elapsed.
"Connacht kicked the ball into touch, and from the resultant line-out, scored a converted try to win the game 20-18.
"However, as time had elapsed, Connacht should not have been permitted to take a line-out throw-in once the ball had been kicked into touch, as stipulated in Law 5.7 (e) of World Rugby's Laws of the Game.
"EPCR would like to thank all parties for their understanding, and would also like to confirm that the result of the Pool Two match stands," concluded the statement.
Going into next month's final two rounds of group fixtures Wasps, Toulouse and Connacht are level on 13 points - with the Irish province third despite having most wins.
Replacement Danie Poolman got Connacht's first try with Jack Carty adding the two conversions and two penalties.
The Wasps tries were scored by Joe Simpson and Josh Bassett with Jimmy Gopperth adding a conversion and two penalties.
