Speculation continues to surround the striker's future after he rejected fresh terms during the close season and remains out of contract next summer.
Beckford's agent Nick Rubery has confirmed a Portuguese club - rumoured to be Sporting Braga - have lodged their interest in his client, who is also being linked with a move to QPR.
"I can't reveal any names, but a Portuguese club have spoken to me about Jermaine," confirmed Rubery to the Portuguese media.
"Beckford's a good footballer and could play for a good club in Portugal. He's playing very well and is focused on his future."
