Ospreys head coach Steve Tandy has paid the price for poor results as the Welsh region confirmed the former PRO12 winning coach will leave with immediate effect as their search for a "world-class" replacement begins.
Ospreys crashed out of the Champions Cup at the weekend after a 24-7 defeat away to Clermont Auvergne and currently sit 22 points behind Munster, who lie in second placed in Conference A of the PRO14.
"Steve has been an outstanding servant to Ospreys Rugby -- often in challenging circumstances," said Ospreys managing director Andrew Millward. "His dedication to the region and his hard work has been absolute.
"However, we're aware that results have not been good enough this season and that, regrettably, a change is necessary to keep the organisation moving forward -- consistent with the long-term expectations of our loyal and valued supporters and commercial partners. In line with this, we will also continue to closely review our entire rugby operation during the coming weeks."
Ospreys are now embroiled in a battle with Connacht and Cardiff Blues to secure the third automatic place for next season's Champions Cup, with the fourth best placed team facing the fourth best placed in Conference B to secure the final spot.
"This is not a decision that has been taken lightly," added Millward. "Steve has been an integral part of everything we have achieved over the last six years -- from winning the PRO12 in his first season in charge to helping develop a strong core of players from our academy -- and before that as a player.
"While our long-term focus is now on finding a world-class replacement and continue building a squad for next season, we have a busy end of season Guinness PRO14 run-in for the coaches and players to focus on."
