Luton's Championship rivals Wigan sack manager Richardson
He hade made a good start to life in the Championship, with just two defeats from the opening 10 games, including a 2-1 victory at Luton in early September.
However, following a 2-0 win a Rotherham on October 1, Wigan have since lost eight games from their last 10 matches to drop down to second bottom in the table with 20 games gone.
Richardson had signed a new contract late last month after a meeting with the club's chairman Talal al Hammad in Bahrain, but a statement on the club’s official website this morning said: “Having looked at the recent run of form that is challenging the team’s status as a Championship club, the board have made the decision to make a change.
“The club would like to place on record it’s thanks to Leam for his efforts and dedication throughout his time at the Football Club, none more so than during the period of administration and his instinctive reaction that helped save the life of Charlie Wyke.
“A much-loved individual and someone who Latics fans will always hold in very high regard, Leam will always be welcomed back at the DW.
“We would like to wish both Leam and his family the very best for the future.
“Assistant Manager, Rob Kelly, will take charge of Saturday’s Championship fixture against Blackpool, with the Club now beginning the process of appointing the next permanent manager of Wigan Athletic.”
