Saracens will not appeal the 13-week ban imposed upon Chris Ashton for biting Northampton Saints prop Alex Waller.
England international Ashton was cited for two counts of biting in Sarries' 27-12 victory in the Premiership last Saturday, which he contested.
After a lengthy hearing on Tuesday, the winger was found guilty of one charge and handed a 13-week suspension.
And the Premiership and European Champions Cup holders have confirmed they will not contest the decision.
"The club has been fully supportive of Chris throughout this process and we are naturally disappointed to lose a player of his calibre for 13 weeks," said Sarries director of rugby Mark McCall in a statement.
"We put forward what we thought was a strong case for both charges to be dismissed but the decision to suspend Chris is one that we accept. No appeal will be lodged.
"We will continue to support Chris during his enforced time away from playing, and help prepare him for his return to action in December."
Ashton was suspended for 10 weeks earlier this year after putting his hand near the eyes of Ulster's Luke Marshall.
Sarries revealed on Friday that wing Savenaca Rawaca, part of Fiji's gold medal winning sevens side at Rio 2016, had pulled out of a move to Allianz Park.
