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.
Bolton youngster Jack Sampson has joined Accrington on a one-month loan deal.
The 19-year-old striker, who enjoyed a spell with Southend last season, is eligible to make his debut for Paul Cook's men at Torquay this weekend and is making no secret of his goalscoring ambitions.
"I'm very happy to come to Accrington," said Sampson.
"Hopefully I can crack on and start the game on Saturday. I've got a little bit of experience at this level and it took me quite a while to get used to the facilities in League Two but I think that'll help me and I can cope well.
"People say loans are to get minutes on the pitch but I want to get goals. I want to try and average a goal a game.
"There was interest from teams lower down this division but I wanted to come to a club with a winning mentality that wants to do well and win games."
