Hooper has signed on loan at Wednesday from Norwich City until January, and as well as paying for the striker's salary, the Owls have also paid £500,000 as a loan fee.
It makes the move a fairly expensive one, but Wednesday will hope that their investment pays dividends over future weeks.
Carlos Carvalhal’s side have been on the lookout for a potent finisher all season, and there is a hope that Hooper can fill that void.
The former Celtic man has been a proven goalscorer in the Football League, and there are hopes that he can fire Wednesday up the Championship table.
The Owls are currently sat in ninth place, and on a nine-game unbeaten run in all competitions, but they have made no secret of their desire to reach the play-offs by the end of the campaign.
Hooper’s first match could come at the weekend, when Wednesday face Nottingham Forest at Hillsborough on Saturday.
