Lions hooker Shane Byrne is poised to make his Saracens debut in tomorrow's friendly against Harlequins at Harpenden.
Irish international Byrne, who joined the Guinness Premiership club from Leinster earlier this summer, has been named among the replacements in Saracens' final warm-up game before tackling champions Wasps at Twickenham tomorrow week.
Former Great Britain rugby league captain Andy Farrell's union debut remains on hold, as he still hasn't recovered from a toe injury.
