Sheffield Wednesday striker Sam Winnall has joined Derby County on loan for the 2017-18 season, with Jacob Butterfield moving in the opposite direction.
Winnall only joined Sheffield Wednesday in January, scoring four goals in 17 Championship appearances for the Owls, including one in two this season.
Butterfield, meanwhile, missed just six Championship games for Derby last season and has already played three times for the Rams this term.
The midfielder will spend the remainder of the 2017-18 campaign at Hillsborough, though, while Winnall also joins Derby until the end of the season.
Winnall becomes Derby's fifth signing of the summer.
