Broncos face test without McCullough

South Sydney coach Anthony Seibold denies Brisbane have taken a gamble by naming lock Josh McGuire at hooker ahead of Friday's NRL clash at ANZ Stadium.

With Andrew McCullough (elbow) out for up to six weeks, McGuire has been thrust into dummy-half.

McGuire has worn the No.9 on just four occasions for the Broncos and Samoa but Seibold said he had the qualities to stand up in the unfamiliar position.
