Italy striker Antonio Cassano has left troubled Serie A club Parma after rescinding his contract.
Huddersfield striker Martin Paterson has joined Orlando City on loan until the end of the season.

Despite Owen's limited playing time, Pulis has ruled out any possibility of Owen leaving the Britannia Stadium on a temporary deal, and will look to give the striker some much-needed match fitness by arranging a friendly behind closed doors next week.

"He needs game time but I didn't think it was right to bring him on against Palace on Tuesday.
"As a manager you have to make these decisions, irrespective of how big a name he is."
