Saracens winger Chris Ashton is in danger of facing a lengthy 12-week ban after he was accused of biting Northampton prop Alex Waller during the recently concluded Aviva Premiership encounter between the two teams at Allianz Park on Saturday.
The incident happened in the first half of the game which Saracens went on to win 27-12 after an impressive performance in the second half.
Despite, there was no action taken during the game by referee Greg Garner, Saracens boss Mark McCall admitted Ashton might be in trouble.
"There is a good chance Chris will be cited, so we will see what happens," said McCall.
"I have heard the accusation. I haven't seen the incident. These things will run [their] course."
Northampton rugby director Jim Mallinder confirmed during the post match conference that Waller has been bitten on his hand .
"Alex repeated at half-time in the dressing room what he said to the referee, that he had been bitten on the hand."
The decision on Ashton is expected to be made on Monday by the citing commissioner Mike Rafter.
Earlier, Ashton was banned for 10 weeks for making contact with the eye area of Ulster's Luke Marshall during the European Champions Cup game last season which ruled him out of the 2016 Six Nations tournament for England.
