JAPIE Mulder and Rassie Erasmus will both start for the Cats in their match against Wellington. Erasmus will play a full match after playing 70 minutes against the Highlanders last Friday, his first match since the World Cup. Erasmus underwent surgery on an injured groin after the rugby showpiece. Mulder will be back after spraining an ankle against the Stormers. Hennie le Roux is expected to move to flyhalf in order to give Mulder space in the backline, with Louis Koen being relegated to the bench.
