Apart from running out in 47 matches for the Lowvelders, the 27-year-old Coetzee has played for the Cell C Sharks and SWD Eagles in a senior career that dates back to 2015.
With Ig Prinsloo out injured, Coetzee – who played for the SA Schools side in 2011 and the SA Under-20s in 2013 – will run out in the New Nation Pumas’ No 3 shirt, next to Simon Westraadt (hooker) and Morgan Naudé (loosehead prop).
Willie Engelbrecht (No 8) and Daniel Maartens (flanker) return to the loose trio, with Francois Kleinhans moving from blindside to openside flanker.
At the back, Etienne Taljaard is back at right wing, while Erich Cronje gets a start at outside centre next to the impressive Ali Mgijima (inside centre).
Eddie Fouché and Chriswill September will continue with their halfback partnership as the New Nation Pumas look to bounce back from their defeats against the Lions (32-28) and Vodacom Bulls (48-31) in the last few weeks.
The 2021 Kick-off Pools match, which will be broadcast live on SuperSport, is scheduled for 16h45 on Friday and Stuart Berry is the referee.
