Aussie NFL star Cameron Johnston signs with Super Bowl favourites the Buffalo Bills

Johnston – a nine-year NFL veteran – had plied his trade with the Philadelphia Eagles and Houston Texans before inking a three-year, $13.6m deal with the Pittsburgh Steelers.

But that stint turned into a nightmare when the Victorian suffered a season-ending knee injury in his Steelers debut – before being cut last month after losing the starting punting job to Corliss Waitman.

But things have worked out well for the 33-year-old, who on Wednesday signed on to play for Super Bowls favourites the Buffalo Bills.

The Bills snapped Johnston up after making a change at the punting position, waiving Brad Robbins.

Robbins had a tough night as the Bills pulled off a week one comeback win over the Baltimore Ravens, and an immediate switch has been made.

The Bills, powered by star quarterback Josh Allen, have been installed as warm favourites to win their first Super Bowl.

The Bills appeared in four consecutive Super Bowls in the early 1990s, but are one of 12 teams to have never lifted the Lombardi Trophy.

They play the New York Jets in week two.
