Far from the bright lights of the Super Rugby cauldron on a tiny field next door to Parliament House, former Wallabies captain David Pocock took the next step towards his comeback from a second knee reconstruction.

While Pocock stepped onto a playing field for the first time, he backed Brumbies inside centre Christian Lealiifano to step straight into the Wallabies No.12 jersey if Matt Toomua doesn't pass his concussion test for this weekend's game against Argentina.

The ACT Brumbies openside flanker said his rehabilitation was on track for a return for the Brumbies' Super Rugby opener against the Queensland Reds at Canberra Stadium on February 13.

He looked fighting fit as he threw himself around the touch football field in the parliamentary sports festival on Monday.
