The Sydney Roosters' Sio Siua Taukeiaho and Brisbane Broncos' Corey Parker go head-to-head in Round 21 of the NRL Telstra Premiership.

The 15th-placed Roosters are playing for pride while the 6th-placed Broncos are trying to get their form back on track ahead of the finals.

The Roosters have scored 53 tries so far this season to the Broncos' 70, and have conceded 75 tries to the Broncos' 57.

Broncos veteran Parker, aged 34, will be aiming for a big finish to his final year of football, while 24-year-old Roosters lock Taukeiaho is hoping to establish himself as one of the best No.13s in the game. Who will come out on top?
