MONTE CARLO, Monaco (AP) _ A decision on steroid suspensions for former Olympic 100-meter champion Linford Christie and two other British runners won't be announced until Monday at the earliest.

A three-man arbitration panel appointed by track and field's world governing body, the IAAF, has spent four days hearing evidence for and against Christie, Doug Walker and Cary Cadogan, who all tested positive for the anabolic steroid nandrolone.

They face suspensions of up to two years.

All three were cleared by the British federation, but the International Amateur Athletic Federation upheld their suspensions internationally pending the arbitration hearing.

``I don't think it will be before Monday at the earliest,'' IAAF spokesman Giorgio Reineri said Friday. ``I think they finished hearing all the evidence yesterday morning and now they are discussing it between them.''

The panel members are Christoph Vedder of Germany, Lin Kok Loh of Singapore and Monty Hacker of South Africa.

There has been widespread debate about nandrolone after suggestions that it can build up in the bloodstream through the intake of legal dietary supplements.

In Christie's case, suspension would be mostly symbolic because the 40-year-old former sprinting star, gold medalist in Barcelona in 1992, has been retired for the past three years. Christie, now a coach, has taken no part in the hearing.

He tested positive for nandrolone while competing for fun at an indoor meet in February 1999.

Walker, the European 200 meter champion, decided not to take part in the British Olympic trials last weekend, while 400-meter hurdler Cadogan has retired.
