The striker, 26, scored his 20th goal of the season as Leeds won 1-0 at Manchester United in round three of the FA Cup on Sunday.
He has been linked with a move away from the League One leaders to Championships side Newcastle.
Beckford, who joined United from non-League Wealdstone in 2006, is out of contract in the summer.
It remains to be seen now what price chairman Ken Bates will look to receive if Leeds are to part company with their prized asset in January.
