Benni McCarthy's move to West Ham has been delayed by work permit issues but is expected to go through over the weekend, according to Blackburn manager Sam Allardyce.
The clubs have agreed a fee for the South Africa striker but there has been a hold-up over McCarthy's permit which is due to expire when his Blackburn contract runs out in 18 months.
It means McCarthy will not be available to play for the Hammers when Blackburn travel to Upton Park on Saturday.
Allardyce said: "It's close to him finally becoming a West Ham player. It's a work permit situation, that's the only hiccup and that should be resolved by Sunday."
