Molloy, in dispute with Rovers and transfer-listed at pounds 50,000, has joined Sheffield for an undisclosed but bargain fee, according to their coach, John Kear.
"Just like Michael Jackson from Halifax, we have been after him for five or six months and he is exactly what we need," Kear said. "He is an aggressive, robust runner who will make us loads of yards and he also has a great off-loading game."
The move is a relief both for Molloy, who had vowed not to play for Featherstone again, and for the game's administrators, who faced the possibility of its registration system coming under a Bosman-style legal challenge.
A measure of relief too for the amateur sides, Featherstone Lions and Siddall, whose five-year bans from all cup competitions have been reduced on appeal.
The two clubs had been punished for a brawl at the end of the Yorkshire Cup final, but Barla, the amateur game's governing body, has cut their sentence to suspension from all its cup competitions, and from representing the amateur game in the Challenge Cup, until September 1999, with a further year's ban suspended.
The televised Saturday match in the fifth round on 28 February will be between Castleford and Bradford. Castleford could be without their centre, Barrie-Jon Mather, who damaged shoulder muscles in last Saturday's victory.
The holders St Helens' match against Warrington will be on BBC2 the following day.Reuse content
