Ablett argued that he had been clumsy and undisciplined, but that the action deserved a free kick only.
Christian assessed it as intentional, low impact and high contact, resulting in a one-game suspension.
The Cats’ decision not to contest the charge is not surprising given Ablett’s recent run of ill-discipline and their desire to give the veteran a rest in any case.
But Geelong coach Chris Scott told SEN radio that everyone at Geelong was disappointed, including Ablett.
“He’s at a bit of a loss to explain why he did what he did especially given the AFL’s been so clear when it comes to any sort of punching acts.”
Scott added though that the rules of the game could be confusing.
“We’re disappointed because we do aspire to understand the rules and play within them as well as any club,” he said.
“The AFL’s been so clear that force is not really a consideration when you punch someone.
“The umpires have been instructed to completely disregard force and pay a free kick so it was clearly that.
“I guess the only thing, if you want to be a little adversarial about it, is that the umpire was watching really closely from two metres away and incidentally paid a free kick but didn’t think it was worthy of a match-day report.”
Ablett has escaped suspensions for much-debated high hits on Essendon’s Dylan Shiel and North Melbourne’s Sam Wright in the past month.
He successfully appealed a one-match ban over the Shiel hit and was not cited for the incident with Wright.
The AFL tribunal won’t sit on Tuesday night after GWS star Toby Greene, Melbourne’s Clayton Oliver and St Kilda’s Luke Dunstan all accepted fines for striking.
