Former Cardiff Blues coach Danny Wilson is set to become the new Scotland forwards coach rather than join Wasps.
Wilson was expected to become the Wasps assistant coach, but it is understood that will not now be the case.
He was set to work under Wasps director of rugby Dai Young, another former Blues coach, but will instead join Gregor Townsend’s coaching team.
The Scottish Rugby Union have agreed a deal with Wasps for Wilson to replace Dan McFarland who is joining Ulster.
Wilson led the Blues to European Challenge Cup glory with victory against Gloucester in Bilbao in May and guided the region to Champions Cup qualification for the first time in four seasons last term.
He joined the Blues as head coach for the start of the 2015/2016 season after previously coaching Scarlets, Dragons, Wales Under-20s and Bristol.
However, he confirmed last September he would not be renewing his contract at the Arms Park after three years in charge.
Wilson’s expected arrival in Townsend’s backroom team could hasten McFarland’s arrival as Ulster head coach after Scotland originally indicated that he would have to work his notice period up until next January before joining the Irish province.
