Russell arrived amid high expectations last summer after scoring 26 goals for Airdrie the previous campaign.
But a knee injury delayed his Scottish Premier League debut until November and he then damaged his cruciate ligament in March.
The 28-year-old has been working hard on his rehabilitation this summer and will aim to hit peak form midway through this campaign.
The former Hamilton and St Mirren player said: "I won't be back for the beginning of the season but I should be back round about the end of October.
"I think I only played nine or 10 games last season so I will put that behind me and batter on this season."
Russell had not played in the SPL before after several years in England with the likes of Mansfield and Macclesfield.
"I think it makes you stronger as a person if you have had to wait a little time to get it," he said.
"I came in and scored a few goals so I'm hungry to do that again.
"I was just getting close to match fit when this happened so I don't think the Killie fans have seen the best of me yet."
Russell was promoting a charity fashion show for the Scottish Huntington's Association at the Radisson SAS Hotel in Glasgow on August 15.
Russell, a part-time model in his St Mirren days, will take to the catwalk to help raise funds to treat people with the genetic neurological disorder, which weakens the body and the brain.
"I've got friends who are involved in the running of the Huntington's Association and it's their 20th anniversary ball," Russell said.
"It's a disease that affects around 850 people in Scotland alone and there are thousands that are unfortunately going to inherit it.
"So the more support they get the better, and the more funds that can be raised for specialist nurses that take care of these people, the better."
