Think the change was largely driven by Yeo HIA mate. When Yeo went off they tried a few in the "ball playing lock" role (Martin, Leniu, Sorensen) and none of them were working well. When Naden came on (~52) Burton moved into halves with May in that ball playing role. Panthers actually looked good at this point and had some decent width. But after playing 50 odd at half then 10 defending in the middle May was way too tired and had to be taken off.
So if Yeo isn't good to go this week we could see May 13 with Burton/Luai halves. Hopefully Cleary is back to solve all the problems
Cleary said in the presser that May was injured early and played on as long as he could.
He also mentioned that Nathan is unlikely to play the Storm - he'd be valuable in that game, but more handy at the end of the season.
Also said they won't rush him in because other players are out (May?).
He said he's going well and looking good, but they don't have a timeline on his return, and when he's ready they'll make that call.
Mentioned that they just need to be smart about that one...
Basically nothing concrete, but implies that Cleary won't be back this week at least, and no guarantees as to how soon it will be
Anyway, if anyone wants to listen for themselves, he talks about Cleary at ~4min 15s in the post match press conference.
