Former Leinster head coach Matt O'Connor has left Leicester with immediate effect after just one game of the Premiership season.
He will be replaced on an interim basis by assistant coach Geordan Murphy alongside coaches Mark Bakewell, Boris Stankovich and Brett Deacon.
O'Connor had been in charge at Welford Road since April 2017 following a spell as a player at the club, but leaves after a 40-6 thrashing at the hands of Exeter on the opening day of the season.
Leicester chairman Peter Tom said: "Matt was appointed head coach in April 2017 on the basis of his previous Premiership experience and his knowledge of the club. But we believe the time is right to make this change in the best interests of the Tigers moving forward."
O'Connor won a Pro12 title with Leinster in 2014 but was sacked at the end of the following campaign. He then had a spell with Queensland Reds in his native Australia before taking the reins at the Tigers.
