Darren Bent insisted he had to leave Aston Villa after too many "slaps in the face".
Brighton defender Greg Halford has agreed to extend his loan deal from Nottingham Forest until the New Year.
Leeds United have confirmed Southend loanee Ryan Hall will sign a permanent deal at Elland Road when the transfer window reopens in January.
The 24-year-old joined on loan from Southend earlier in the season and has made five appearances for Neil Warnock's men so far.
The Whites announced Hall will pen a two-and-a-half-year deal in the new year to become the first permanent signing under the club's new owners GFH Capital.
Warnock told Leeds' official website: "When we brought Ryan in I said 'I believe he is a player with potential for a big future.'
"I'm sure during the length of his contract Ryan will have the opportunity to establish himself at this level, and you can see that from his contribution at Huddersfield a few weeks ago.
"It's not just experienced players we are looking for to add to the squad, and if we feel there are youngsters like him available at the right prices we will look to the future as well."
