UPDATE 1-Soccer-Former Norwegian boss guilty of fraud over Mikel

(Adds details, quotes)

OSLO, March 26 (Reuters) - Morgan Andersen, former director of Norwegian club Lyn, was handed a one-year suspended jail sentence by an Oslo court on Wednesday for forging contracts relating to Nigerian midfielder John Obi Mikel in 2005.

The court said the falsified documents linking Lyn and Mikel, who went on to become embroiled in a transfer row between Premier League clubs Manchester United and Chelsea, effectively enabled Lyn to gain a slice of the player's transfer fee.

"The court is in no doubt the contracts were amended and Andersen knew this," judge Torjus Gard said in his judgement.

Andersen told the court he would lodge an appeal.

Lyn director Erik Langerud called the verdict "unfortunate" but told local media he did not think it would hurt the club financially.

Langerud told the online version of tabloid VG that he did not think the verdict would force Lyn to pay back millions of pounds in transfer fees.

"We must just wait for this judicial process, which is continuing, and see what happens in an eventual appeal and cannot take a stance on one thing or another before it is decided -- and before any eventual case against us," he told VG.

Mikel was under 18 when he joined Lyn and was therefore given an amateur contract.
