The 22-year-old former Natal Sharks player has yet to feature for Albion after picking up the injury in the club’s pre-season match against Newton Abbot.
There were worries that Fisher’s Plymouth career might be over before it had even begun but he has worked hard to try and get back and he is now on the verge of a return.
“I am still doing rehab but I am back in training this week,” he said. “I’m back in contact training and everything, so happy days.
“I’m going to play against Taunton on Tuesday (in a development game) and, hopefully, I can get back into the first team after that.”
Fisher admitted the timing of his injury was very frustrating, coming so close to the start of the season and having just arrived in the country.
“Doing it in a warm-up game and the last one before the league start, was really irritating,” he said.
“Watching the boys train and play games from the side of the field is very frustrating, but I’m back now and the knee’s good, so everything is fine.”
Fisher admitted the injury has been a worry.
“You always get bad thoughts in the back of your head, like is the knee going to hold up once it’s ready? Will I have to go back home? Am I going home?
“But I think now it is a mind thing. I have to keep my mind strong and positive. If I do that I’m sure I will be fine.”
He added: “There’s nothing worse than watching boys play, so I can’t wait to get back on the field and do some damage.
“There’s nothing better than match fitness, so I want to stay on the pitch as long as I can on Tuesday.”
Fisher knows he is going to have to work harder than ever now to get into the first team after missing the first two months of the season.
“There is a lot of competition, so I will have to really put my hand up in the next couple of weeks leading up to the next game after our weekend off,” he said. “But I’m going to give it everything and hopefully get into that side.”
