Blackburn Rovers boss Sam Allardyce is keen to help Nathan Ellington rebuild his career.
The 28-year-old striker is in the final year of his contract with Watford after a season on loan with Derby, and has been told he can find a new club.
Allardyce said: "I like to try and resurrect somebody.
"This is a lad with a huge amount of talent and has a really good CV from his time particularly at Wigan."
The Rovers boss added: "He's only 28 so whatever went wrong, if we can put things right we'll have a real player on our hands but he has to prove it in the few days he is with us."
