In the original comic series, Rick's right hand was cut off by ruthless villain The Governor.
However, Kirkman told reporters at the 2011 San Diego Comic-Con: "One thing I'm adamant about is I don't think that we should cut Rick's hand off [on television]."
He explained: "When I'm writing a comic book, I don't think about what I'm doing. I go, 'Oh, it'd be pretty cool if they cut his hand off right now. That'd be pretty shocking, right?'. Then I do it, and five issues later, I write 'Rick opens a can of beans' and then I look at the script and think 'He can't do that now'. I didn't even think that through."
Despite the proposed change, Kirkman added that there are "very few things" he regrets about the Walking Dead comic.
"One of the things that's great about the television show is [it features] a lot of characters I miss," he said. "I don't regret killing them, because I recognise its value to story, but to be able to come back and write them again... has been awesome."
The second season of The Walking Dead will premiere on AMC in October and air in the UK on FX in late 2011.
