Jason Shackell is a tall left-footed centre-back from Stevenage who progressed through three years of Norwich's academy.

He signed a two year professional contract towards the end of January 2003. He became the first home-grown player to sign a long-term deal for five years. For though Aylsham's Lewis Blois was handed a one-year professional contract to prove his worth, Darel Russell was the last Colney product to sign for longer - way back in November, 1997.The hope is that the security of a two-year contract will allow Shackell to blossom into a regular member of Worthington's first-team squad. "The boy deserves the two years," said Worthington. "It takes the pressure off him. Rather than just having the 12 months, he's got 24 months to go and produce." Size, maturity and a good left foot are three good reasons why the teenager can now look forward to a professional career at Carrow Road. "He's a good size for a centre-half," said Worthington, with Shackell standing a good 6ft 2in tall. "Plus he's matured over the last 12 to 18 months, both as a player and as a young man. He's joined with the professionals in training and held his own very well and I wouldn't have any problem with putting him in if the situation arose."

Jason became the third Academy player, after Ian Henderson and Dean Sinclair, to make his first team debut during 2002/03 when he played against Derby in a 2-1 defeat on March 5th 2003 replacing Adam Drury at the last minute when Drury succumbed to a virus.

Shackell was appointed the club's captain for the 2007/8 campaign and signed a new contract in October 2007 keeping him at Carrow Road until 2010. He lost the captaincy to Mark Fotheringham after Glenn Roeder was appointed manager

In July 2008, he was the subject of a £1m bid from Wolves but this was rejected by Glenn Roeder as the Canaries only had 4 recognised defenders in their squad at the time of the enquiry.

On 1st September 2008, Jason finally moved to Wolves, signing a four year contract for a fee rumoured to be between £750,000 and £1million.
