Yeah I’m not a physio but my understanding is that hamstring stuff is right up there in terms of likelihood of re-aggravation or turning into something worse.
Brown should be sweet to come back in round 7 at the latest, so at the very worst we’ll roll into that game 3-3 with a spine of Fletcher Sharpe, Sandon Smith, Dylan Brown, Phoenix Crossland and maybe a bit of Harrison Graham. Which is still honestly really good. And I back us to pick up one of the next two at least with how we’ve been playing, so we may be doing even better than that.
There’s no reason to be desperate to rush Kalyn back if those other guys are fit.
