Watford have released Steve Kabba and are waiting for Derby County to make a decision on Nathan Ellington.
Kabba joined Watford in January 2007 from Sheffield United, but has recently been on loan at League One side Oldham Athletic.
The striker is now on the look-out for a new club after the Hornets confirmed his contract has been cancelled by mutual consent.
Meanwhile, Watford have yet to receive an official response from Championship rivals Derby regarding the future of Ellington.
He has spent the season on loan at Derby, but has barely featured since Nigel Clough took charge and has been told he has no long-term role at Pride Park.
However, the Rams have the option of signing the forward on a free transfer and could then sell Ellington on, with Watford awaiting an answer.
Hornets chief executive Julian Winter told the Watford Observer: "We haven't had a definitive answer from Derby. If he does come back then we will deal with it as and when we have to.
"Our manager [Brendan Rodgers] has made it clear that Nathan is not for him, so everyone knows what we want to do."
