Veteran striker Paul Dickov will spend "a couple of days" training with Leeds this week.
Dickov, 37, whose previous clubs include Arsenal, Blackburn and Manchester City among others, was released from Leicester last week.
Leeds manager Simon Grayson said: "Paul came in on Monday and he's going to train with us for a couple of days.
"I've known Paul a long time and he was with me at Blackpool. We'll see how things go."
