BRONCOS hooker Andrew McCullough is facing up to six weeks on the sidelines after suffering a hamstring injury against the Rabbitohs.

McCullough’s left knee hyperextended in an awkward tackle by Rabbitohs giant Tom Burgess during last Friday’s 30-8 win at Suncorp Stadium.

It looked as though the gutsy dummy-half may have suffered a serious knee injury but he was cleared of structural damage.

Scans over the weekend revealed McCullough suffered a tear to the hamstring tendon and will miss up to six weeks.

While it could have been worse, McCullough’s absence is a major blow for the Broncos.

He has played 183 NRL games since debuting in 2008 and has missed very few in that period.

The Broncos will be hoping McCullough is fit to return before the Origin series begins on June 1, given Brisbane will have a healthy representation in the Queensland team.

Journeyman Travis Waddell is expected to come into calculations to start in the No. 9 jersey against Cronulla next Sunday, having played for Souths-Logan in the Intrust Super Cup so far this season.

Kodi Nikorima is expected to stay on the bench. Other hooking options are Jai Arrow and Jayden Berrell.
