Melbourne Storm's Cameron Smith delivered a captain's knock on Friday to give his team every chance of a top four NRL finals berth with a drama-packed 22-12 win over Brisbane at AAMI Park.
Smith shrugged off a possibly serious ankle injury that temporarily forced him off the field while centre Mahe Fonua scored two second half tries to seal the last round win and a place in the play-offs.
The Storm moved into fourth, however Penrith and North Queensland can still leap-frog them with wins against the Warriors and Manly respectively.
Brisbane meanwhile could drop out of the eight should the ninth-placed Warriors or 10th-placed Parramatta, who face the 15th-placed Canberra on Saturday night, win.
Smith left the field with 11 minutes remaining in the first half with the injury diagnosed as syndesmosis - a high ankle sprain which usually means at least a week out.
