Two rugby greats are set to bring down the curtain on their careers at Twickenham on Sunday.
Harlequins prop Jason Leonard and Springbok second row Mark Andrews will hang up their boots following their selection for the Barbarians against a scratch England side.
Leonard - who announced his retirement from all rugby earlier this month - is the most capped player of all time with 114 England appearances and is sure to receive a rousing reception at Twickenham.
One of Sir Clive Woodward's World Cup winners, the 35-year-old British Lion has proved one of of the sport's most durable figures - despite operating in the toughest of positions - and is a highly popular figure.
Andrews, another player to get his hands on the Webb Ellis Trophy, won 77 caps for South Africa during a glorious seven-year spell in the Test arena which saw him earn a reputation as one of the finest forwards of the modern era.
He finished his club career with Newcastle but was dogged by injury for the two seasons he spent at Kingston Park, although he has been given one more chance to say goodbye - against the side he faced on his Springbok debut.
Former All Black hooker Anton Oliver will skipper a Barbarians team which has amassed 688 caps and includes five former or existing international captains.
Ireland centre Brian O'Driscoll lines-up in the midfield and is joined by his fellow Triple Crown winners Shane Horgan, David Humphreys and Malcolm O'Kelly.
Saracens' French international Thomas Castaignede has been pencilled in at full-back but will undergo a late fitness with Wallaby Matt Burke on standby to take his place.
Team: T Castaignede (Saracens & France), S Horgan (Leinster & Ireland), B O'Driscoll (Leinster & Ireland), N Grey (NSW Waratahs & Australia), B Reihana (Northampton & New Zealand), D Humphreys (Ulster & Ireland), M Robinson (Northampton & New Zealand), J Leonard (Harlequins & England), A Oliver (Otago Highlanders & New Zealand), C Visagie (Saracens & South Africa), M O'Kelly (Leinster & Ireland), M Andrews (Newcastle Falcons & South Africa), O Finegan (ACT Brumbies & Australia), A Vos (Harlequins & South Africa), T Randell (Saracens & New Zealand).
Replacements: M Sexton (Ulster), G Feek (Auckland Blues & New Zealand), O Magne (Montferrand & France), B Skinstad (Newport Gwent Dragons & South Africa), N De Kock (Western Stormers & South Africa), D Traille (Pau & France), M Burke (NSW Waratahs & Australia).
England flanker James Haskell insists he will be pushing as hard as possible to be back from a toe injury in time to make his case for a spot in Eddie Jones' side looking to defend their RBS 6 Nations title next year.
