The loanee has joined from Norwich City until January.
The former Celtic striker has fallen down the pecking order at Carrow Road and was desperate for first-team football elsewhere.
The Owls swooped in and picked him up on a loan deal until January 17th.
The striker has not however played a game of football since August and has also had a niggling injury to contend with.
So ahead of a potential first game for the club against Nottingham Forest at the weekend the new Owls signing has had to admit that he is not yet at 100% - and would understand if he did not start the game.
“The gaffer can’t change it straight away.
"He’s got strikers who are playing well, scoring goals and helping the team get results so hopefully I can add to that.
“It’s the gaffer’s choice in the end who plays. I’ve got to train hard to get in the team.
“I have not played much this season so I’m not 100%.
“Now I am fit and raring to go. I want to play football and score goals. That’s why I am in the game.”
Wednesday are certainly spoiled for choice up front. Lucas Joao is in form, Fernando Forestieri back in for selection whilst Atdhe Nuhiu and Sergiu Bus would also like to feature.
Hooper may have to settle for a place on the Wednesday bench this weekend but as soon as he gets the chance have no doubt that Hooper will be looking for the back of the net.
