Blackburn Rovers boss Sam Allardyce has not ruled out the possibility of Nathan Ellington becoming his latest signing.
The 28-year-old former Wigan Athletic and West Brom striker is currently in the final year of his contract with Watford after spending last season on loan with Derby County.
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.
"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."
Allardyce has also revealed that David Dunn and Vince Grella will miss the start of the season, adding: "It's a growing concern as they've started this pre-season where they left off last.
"We particularly wanted those two players to get through a full pre-season because Vince had his first year disrupted by niggles and pulls.
"Dunny ended up missing the back part of last season to get the operation to get fit.
"Thankfully it's nothing to do with the Achilles tendon, it's only a bit of a thigh but he's missing days where he should be out with the rest of the lads."
