Sheffield United have sacked first-team manager David Weir following the club's disappointing start to the Sky Bet League One season.
The Blades have won just one of their 10 league fixtures this term, with that coming on the opening day, and currently sit third from bottom in the table with just five points.
Former Scotland and Everton defender Weir, 43, was only appointed in June, taking up his first job in management.
But his stay at Bramall Lane has not lasted long having been relieved of his duties along with assistant boss Lee Carsley.
Chief executive Julian Winter told the club's official website: "First and foremost all at SUFC, from the board right the way through the club, wish David and Lee all the best for the future.
"None of us wanted to be in this position at this point in the season. David's appointment was made as part of developing a new phase at the club."
United's under-21 coach and former Blades defender Chris Morgan, goalkeeping coach Darren Ward and head of academy coaching Travis Binnion will take charge of the team on an interim basis - starting with Sunday's televised trip to Sixfields to face Coventry.
The South Yorkshire club insist they aim to appoint a new management team on a permanent basis as quickly as possible.
Winter added: "Chris Morgan has been asked and agreed to take an interim role in charge of Sunday's team. He knows the players and, with Darren and Travis, will be doing his utmost to get a return to winning ways."
Meanwhile, Morgan added: "The club have made me aware of the situation and I am happy to step in and work with the players for the Coventry game."
Weir replaced Danny Wilson in the summer but endured a baptism of fire in his first management role, losing nine of United's 13 matches in all competitions.
Saudi Arabian Prince Abdullah bin Mosaad purchased 50 per cent of the club's share from owner and chairman Kevin McCabe last month and gave Weir his full backing.
But the club's fans have consistently expressed their concern at such a poor start to their third season in the third tier, which has seen the Blades lose five of their last six games.
