Influential Exeter player Dave Ewers may miss the play-offs after citing a dangerous tackle on Ciel defender Simon Hammersley on Saturday.
After reviewing television footage, referee Karl Dixon gave Ewers a yellow card in the first half, which saw Ewers’ shoulder make a hard contact with Hammersley’s head.
If found guilty, Ewers could receive a ban that would end his season.
Teammate Sam Skinner faces similar charges after a second-half red card.
Skinner was sent off from the second row in Scotland 13 minutes into the second half when his shoulder made contact with Fav de Klerk’s head – referee Dixon felt there was no mitigation for Skinner’s tackle while he felt Hammersley was spinning after an earlier tackle before Ewers could make contact.
The two players will appear before an independent disciplinary committee on Tuesday, with a six-week ban as a starting point if they are found guilty.
