Investigation into missile-throwing by Hull KR fans at end of play-off defeat

Hull KR have had three players called up to England's Four Nations training squad, but could face punishment from the Rugby League over their fans' missile-throwing at Wigan on Friday.

The home players had to retreat to the halfway line, rather than standing behind the goalposts in the normal manner, towards the end of Rovers' play-off defeat. A number of objects were thrown on to the pitch from the away end, including parts of the "clappers" handed out by the sponsors. The League is waiting for reports from the referee and match commissioner before launching an official investigation.

Meanwhile, two Rovers' newcomers have been added to Steve McNamara's squad to prepare for the autumn internationals, along with the more established Peter Fox. The stand-off, Scott Murrell, was man of the match in the Robins' play-off victory over Hull, whilst forward Liam Watts was named last week as Super League's rookie of the year.

Warrington, also knocked out of the play-offs this weekend, have had no less than eight players named in the squad, with the winger, Chris Riley, the least experienced at representative level.

There is bad blood between Wigan and Leeds before their second meeting in the play-offs this Saturday. Leeds won by a single point in their first match, but lost their Test stand-off, Danny McGuire, with a serious knee injury in the last play of the match.

Comments made about the circumstances of the injury – McGuire was obstructing Wigan's George Carmont – have inflamed things. The Sky TV pundit – and former Wigan player and chief executive – Phil Clarke, wrote in his column that McGuire's misfortune was his own fault. "Perhaps the rugby gods were punishing him for his unsportsmanlike play," he wrote.

The Leeds coach, Brian McClennan, has called them "tasteless comments which really disappoint our club," and it is understood that McGuire has snubbed Clarke's attempts to apologise.

Now Leeds' injured England captain, Jamie Peacock, has added fuel to the fire by calling two Wigan players, Mark Riddell and Thomas Leuluai, "cowardly" for confronting McGuire as he lay injured. He predicted that the Rhinos' players will remember that come Saturday.
