Hull KR have lost their appeal against Joel Tomkins’ ban, and the club captain has had his suspension increased to two matches.
London recorded a surprise victory at Hull KR to keep their Super League dream alive
The former Wigan back rower will now miss the match against Salford Red Devils which could decide KR’s Super League future, and his two-match ban will be carried over into the close season.
Rovers are one of four clubs locked on 20 points and in danger of relegation going into the final round of the regular Super League season.
It is the second time Tomkins has been forced to miss an important game this year because of suspension.
A one-match ban ruled him out of his team’s Challenge Cup quarter-final against Warrington in May, which they went on to lose.
