McGahan, aged 34, last played in 1991, and said: "There is no way I will play again after four and a half years - although I have told the players that I probably couldn't do any worse."
The case of Bell, who played for Auckland Warriors less than a year ago, is subtly different. "He doesn't want to play, but he will be able to if necessary," McGahan said.
The New Zealand Test stand-off, Tony Kemp, was making his return from a broken arm in the Alliance team last night. If he suffers no reaction, he is in line for a place on the bench tomorrow against Wigan, who will be without Va'aiga Tuigamala with a hamstring injury.
Leeds will be without two of their forwards, Adrian Morley, who was suspended for one match last night after being sent off for a swinging arm at Bradford last week, and Harvey Howard, banned for four games after being called to account on video evidence for a similar offence in the same match.
Evan Cochrane, the London Broncos centre, has been banned for three games for the punch that saw him sent off at Warrington. Cochrane has been fined pounds 4,250 by his club.Reuse content
