It appears that Antonio Winterstein will be out for four-to-six weeks, with scans reportedly confirming that he sustained a broken forearm in last night's clash with the Broncos.
The winger picked up the injury in the 13th minute of play and came straight from the field.
Coen Hess came on in the reshuffle, with Ethan Lowe moving to centre and Justin O'Neill to the wing.
The loss of Winterstein may result in young prodigy Kalyn Ponga getting a run for the first time since his two-game streak in the finals last year.
Ponga has received a fair bit of press, mostly due to his HUGE deal with the Knights for next season.
