Tom Lees has extended his contract with Wednesday, staying with the club until the summer of 2021.
Lees has been the subject of recent media speculation but has committed to the Owls for the long term.
The 25-year-old joined Wednesday in July 2014 and has since proved a rock at the heart of the rearguard.
Lees has made 88 appearances for the Owls, chipping in with three goals along the way.
