West Ham's bid to sign Benni McCarthy has been delayed due to work permit issues, although the deal is expected to be rubber-stamped by the end of the weekend.
The Blackburn striker is primed to seal his switch to Upton Park 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.
McCarthy could have been in line to make his debut for his new club against Blackburn on Saturday, but such an unlikely scenario has now been ruled out.
Blackburn boss Sam 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."
McCarthy infuriated Allardyce by not turning up for training in order to force through a move but Rovers midfielder David Dunn said the South African would not "lose much sleep" over leaving the club under a cloud.
"Sometimes things like that happen, it's perhaps not always the best way but I'm sure Benni will not lose too much sleep over it," Dunn added.
"There has been a bit of attention on Benni over the last week but maybe he feels this is the right career move for him.
"He has been a good goalscorer for the club and is a good lad as well so I wish him all the best."
