Bulldogs forward Chris Smith has hope of playing again in 2020 after scans showed he didn't fully rupture his ACL while playing for the Indigenous All Stars.
Canterbury said Smith will have surgery this week and miss at least 12 weeks having suffered a partial ACL tear and a complete MCL tear.
Fullback Dallin Watene-Zelezniak was cleared of serious injury after bruising his back during the Maori team's All Stars win.

New signing Adam Doueihi went off in the Tigers' loss to Penrith with an upper leg injury but coach Michael Maguire after the game said Doueihi's exit was precautionary and he'd be fit for the next trial.
Having already lost Bunty Afoa for the season, the Warriors have potentially been dealt another blow to their front-row stocks with Jackson Frei injuring his knee in the trial game against the Storm.
Frei lasted just 14 minutes in Palmerston North and will sweat on scans as the Warriors prepare for their final trial against Wests Tigers next Sunday.
