The object of today's exercise is to gain a victory to maintain the momentum and to ensure that those involved in next weekend's Test come through unscathed.
Winning shouldn't be much of a problem against an invitational side coached by Alan Solomons that includes Harlequins centre De Wet Barry, Leicester Tigers lock Marco Wentzel and Bristol wing Matt Turner with former Springbok outside half Jaco van der Westhuyzen partnering Bulls scrum half Francois Hougaard.
McGeechan and Co will be hoping the Lions can get the job done without having to involve the replacements six of whom will be in contention for a place in the Test 22.
Lions: Keith Earls; Ugo Moyne, Riki Flutey, Gordon D'Arcy, Luke Fitzgerald; James Hook, Mike Blair; Andy Sheridan, Ross Ford, Euan Murray; Simon Shaw, Donncha O'Callaghan capt; Nathan Hines, Joe Worsley, Andy Powell.
