The Nigerian striker turned up at Loftus Road on Thursday night and spoke of his new challenge ahead playing for the R's but the Baggies had never agreed a deal with QPR and he was forced into an embarrassing return to the Hawthorns.
Baggies chairman Jeremy Peace issued a statement admitting the whole situation was an "unsavoury affair" for all involved.
"This evening's developments have brought a conclusion to what has been an unsavoury affair," he said.
Meanwhile, Redknapp denies QPR had anything to do with him arriving unannounced at the club, and he told Sky: "I think he probably felt that the deal had been agreed between the clubs and it hadn't and it was all a mix up really.
"I feel sorry for the lad and the way the whole thing's turned out. It wasn't any of our doing. I think he was maybe advised that he should turn up here and that the club had made an offer and the offer had been accepted.
"The wires got crossed somewhere."
