The coaching staff did remark that the scratches are only temporary, so we should expect to see O'Sullivan back in the line-up on Saturday, but its hard to say about Stortini.
In the Draft, O'Sullivan is the only player of note for any implications and he was taken by Allan this year. Allan is in a battle with Ryan for 9th spot, but still has a 14-point gap up to 8th spot, so a healthy scratch like that wasn't going to help. His return will be greatly appreciated though.
On the Sheet, O'Sullivan wasn't taken at all, but there are eight teams in the pool that were happy that Comrie came back. So, there's more of a positive than a negative there.
