Wales and British & Irish Lions centre Jamie Roberts will play for Cambridge University in Thursday's match against Oxford University at Twickenham on Thursday (kick-off 14:30 GMT).
The 29-year-old, capped 77 times by Wales, will become the first active international to play in the match since Australian Dan Vickerman in 2009.
Scrum V presenter Ross Harries met Roberts to discuss the rituals of being selected and the pressure of trying stopping Oxford from securing a record sixth win in a row.
