WATCH: Joe Marler could be facing another ban after an alleged kick to the head
Harlequins booked their place in the European Challenge Cup final tonight but they may have to play the decider without international prop Joe Marler after the loosehead appeared to make contact with an opponent's head on the ground.
Marler was involved in an altercation with Grenoble hooker Arnaud Heguy during Quins' facile 30-6 victory, but the occasion was marred by the incident where Marler's boot connected with the Frenchman.
The England international is just back from serving a two-game ban for calling Welsh prop Samson Lee 'gypsy boy' during the Six Nations, but this latest indiscretion could prove even more costly.
England have a three-match tour to Australia in the summer, but if Marler is cited for a kick after tonight's game, then he will almost certainly miss out.
Tries from Nick Evans, Jamie Roberts and George Lowe saw Quins ease into the European final at the Stoop tonight, where they will play the winners of tomorrow's second final four clash between Montpellier and the Dragons.
Conor O'Shea will be hoping to win the tournament for a second time with the English club before he leaves to take over the Italian national team in July.
