The Ulster-based looseforward was in the running to make it to the tournament for the first time having also missed out in 2015. But he sustained the injury playing against Argentina at Loftus last Saturday.
Coetzee‚ who covers all three looseforward positions‚ would’ve been the ideal player for a World Cup squad due to his versatility. Another four players from the 36-man squad invited to Bloemfontein on Sunday‚ were also released back to their provinces to play in the Currie Cup this weekend. Prop Lizo Gqoboka ‚ lock Marvin Orie ‚ prop Thomas du Toit and centre André Esterhuizen were the four players released‚ which is an indication that they will miss out on the final 31-man squad to be named next Monday.
