HIGHLANDERS flyhalf Tony Brown is unlikely to see action in his team’s Super 12 clash with the Auckland Blues on Friday night after spraining his ankle on Sunday. Highlanders’ coach Peter Sloane said that Brown is doubtful for the match and there are more worries in the backline. Rua Tipoki, who rolled an ankle against the Brumbies, has a fifty-fifty chance of playing, while Romi Ropati may start the match.
