Reports suggest Sheffield United have handed trials to three promising Jamaican youngsters.
Demar Stewart, Jason Morrison and Rafe Wolfe all play for Portmore United and are spending a week with Neil Warnock's squad.
Warnock is expected to look at the trio during a behind-closed-doors friendly between the Blades and Leeds United.
Stewart is a 22-year-old defender, while Morrison, also 22, plays in midfield. Twenty-one-year-old Wolfe has represented the Reggae Boyz at Under-23 level.
It is believed that Warnock will loan the players to clubs in Holland or Belgium while keeping first option on them, if he decides they have a part to play in his long-term plans at Bramall Lane.
