Botha handed Namibian start
Chysander Botha will play at his home ground of Sandy Park on Tuesday after being named in Namibia's side to face Tonga (4.45pm).
The Exeter Chiefs full-back has been promoted from the bench after going on as a replacement in Thursday's 58-14 defeat to New Zealand.
Despite signing for the Chiefs back in July 2014, the 27-year-old has only made five appearances for the club's senior side following a broken leg and dislocated ankle he suffered while playing for his country against Canada.
Only two of those appearances came at Sandy Park, meaning this will be just the third time he has played at the Exeter ground.
However, he will not come up against Chiefs team-mate Elvis Taione after the hooker was not included in Tonga's matchday squad for the Pool C encounter.
Taione, 32, is one of nine changes made by the Tongans following their disappointing 17-10 defeat to Georgia.
That number is the second-most ever made by Tonga between successive World Cup matches – they made 11 changes between their first and second match at the 2011 tournament.
Despite a shaky showing, Fetu'u Vainikolo retains his place in the side for the Namibia clash after going clear at the top of Tonga's Test-match try-scoring list with his effort against Georgia.
That put him on 15 Test tries for his country, taking him one clear of previous record-holder Josh Taumalolo.
The 327 Test caps shared amongst Tonga's line-up are also their most ever in a World Cup match.
