The 26 year-old suffered an injury to his thigh in the 1-1 draw with Everton at Goodison Park last November and subsequently underwent surgery.
Since then, Canaries boss Chris Hughton has had to rely on former Blackburn Rovers keeper Mark Bunn between the sticks.
Speaking about his return, Ruddy told Sky Sports: “It has gone really well, there have been no problems so far. I start full training on Thursday, which I am very much looking forward to.
“It has been really frustrating for the last four-and-a-half months so it is going to be nice to be out on the fields with the lads again. I am very much looking forward to it and I can't wait to be back in action.

The former Everton man won the Canaries' Player's Player of the Season award following Norwich's 12th-placed finish last term and was forced to pull out of England's Euro 2012 squad due to a broken finger.
With Bunn suspended for the upcoming clash at Wigan Athletic and third-choice goalkeeper Lee Camp will set to make his first start for the club, Hughton will be anxious to see Ruddy regain full fitness.
He added: “It is fairly quick for a goalkeeper to be back from this type of injury. With the amount of kicks and the distance I am kicking every game, that is the main aspect we have been focusing on.
“I am eager to get back and hopefully that will be in a few weeks.”
