The Notts County midfielder, who was Knill's first signing since joining the club, trained with his team-mates on Thursday and is available for selection having signed a loan deal until the end of the season.
Knill has also been handed an injury boost with the news that experienced defender Aaron Downes could return to action after a hamstring injury. The 27-year-old limped off with the injury in Torquay's 1-0 defeat to Port Vale last week.
Midfielder Craig Easton (calf) remains out while Southend loanee Elliot Benyon continues to have treatment for a sore knee but he is likely to partner top scorer Rene Howe again.
Knill revealed they are managing Benyon's niggling injury and have been resting him between games.
Torquay are without a win since January and sit two points above the npower League Two relegation zone.
