The winger was forced out of the 2-0 defeat to Tottenham last time out after suffering an ankle problem.
But the 25-year-old had an injection to help alleviate the problem and is keen to face Rangers at Molineux.
"It's been managed well and the injection has sorted it now, so I just want to carry on training and try to get back into the team," Jarvis told the Express and Star.
"I'm 100 per cent fit and I want to carry on where I left off after a good start to the season.
"I hadn't been training fully up until the Spurs game because of the ankle. It wasn't fair having not trained to then play."
