Only saw one possible error, late in the second half
Pumas put up a bomb into the Boks 22m. Green 15 (le Roux) jumps for the ball, and Green 11 (Habana) gets sandwiched between him and a Blue chaser. Le Roux calls for mark, and Habana is hurt
IMO, Habana should have been pinged for obstruction (prevented Blue player from competing for the ball)
