Garry Monk is the new manager at Wednesday.
The former Swansea, Leeds, Middlesbrough and Birmingham boss was unveiled at a Hillsborough press conference this afternoon and his first game in charge will be the televised away clash at Huddersfield on September 15.
In his playing days, Monk made 15 appearances for Wednesday as a central defender on loan from Southampton in the 2002-3 season, under Chris Turner in what was then division one, now the Championship.
Lee Bullen has been in charge in a caretaker manager capacity since Steve Bruce quit in the summer to join Newcastle and, after an encouraging start to the season, there were views in some quarters that Bullen should be appointed in a full-time capacity.
However, three defeats in his last four leaque games will have dented his hopes of landing the job and now chairman Dejphon Chansiri has turned to Monk, 40, who has more experience of managing at Championship level.
Monk is the fifth Wednesday manager since Chansiri became owner and chairman early in 2015, following in the footsteps of Stuart Gray, Carlos Carvalhal, Jos Luhukay and Steve Bruce.
