Despite contesting the report at the AFL tribunal, Mumford was rubbed out for two weeks for rough conduct after a vigorous tackle on Ablett in round seven that left the Cat champ dazed.
Ablett recovered to produce a best-on-ground performance that day, but Mumford was banished to the stands for the next fortnight as the Swans lost successive clashes against the Western Bulldogs and Fremantle.
However, the big ruckman said he wasn't going to change his robust approach to the game.
"I think I was just unlucky to be the first one to cop it, really," he said.
"I'm still going to go out there and tackle the same way each week and if I get pinged for it again, I get pinged again but hopefully that won't happen."
Mumford said he was surprised to learn that he had been reported for the incident and his opinion didn't change on viewing the replay.
"I was fairly shocked, as were most people who watched it, but they deemed it differently so I've just got to take it on the chin," he said.
"We watched the DVD at the start of the year that said the umpires were going to be looking at sling tackles and things like that, which I didn't actually think mine was, but I can't do much about it now."
Mumford returned against the Hawks in round 10 and had an immediate impact, racking up 17 possessions, 42 hit-outs and six tackles in the narrow loss at the MCG.
He said it was a relief to be able to return to the field and help his teammates out as they strived to break their losing streak.
"It wasn't much fun sitting on the sidelines. It's always tough watching your side, especially when you're getting beaten," he said.
"The first game wasn't so bad because I was carrying a bit of an injury from the Geelong game but the second game was horrible, sitting up there knowing that I was 100 per cent ready to go and I just couldn't do anything about it."
While Mark Seaby's continued absence is a blow to the Swans, Mumford said the opportunity provided to rookie ruck Mike Pyke was a positive arising from his teammate's misfortune.
"It was good with the combination I had with Seabs, as we were both playing even game time, but Pykey has stepped up, especially in the games that he played in his own," he said.
"I felt that he carried himself really well. It's a good thing knowing that we've got another ruckman there if me or Seabs do go down in the future."
And Mumford conceded that he would also reap some reward from the extra responsibility placed on his shoulders as the Swans' No.1 ruckman in the coming weeks.
"That was the biggest thing for me about coming up here [from Geelong] - the fact that I would be playing every week," he said.
"Now that I'm going to be playing big minutes, it's only going to benefit my footy and I'm already starting to see that."
