The Maroons odds for winning Origin One have drifted with TAB following reports that star fullback Kalyn Ponga is expected to be ruled out with injury.

Queensland had tightened from $2.45 into $2.20 after Ponga and Cameron Munster’s inclusion in the side, Townsville replacing the MCG as Game One host and Felise Kaufusi avoiding suspension.

Since then they have reverted back to their starting price of $2.45 with doubts over Ponga while the Blues remain favourites to take an early series lead at $1.55.
