Calum Davenport joined Norwich on loan from Tottenham Hotspur on 13th September 2005. The 22 year old central defender joined the Canaries for three months after failing to break into the Spurs first team. He began his career at Coventry, debuting at the age of 18, and winning England Under-21 caps. He made 84 appearances for the Sky Blues before Tottenham paid an undisclosed fee for him in the autumn of 2004. He spent parts of last season on loan to West Ham and Southampton. He made his debut in the 2-1 defeat at Watford on the 13th September.

Calum returned to White Hart Lane in mid-December but with Norwich manager Nigel Worthington keen to bring him back to Carrow Road either permanently or on another loan. On 1st January 2006, Calum was linked in The People with a £800,000 switch to Reading. On 17th January 2006, he was linked with a £1million move to Sheffield United. The League Paper then reported on 19th March 2006 that Davenport and Coventry's Gary McSheffrey topped Reading's transfer targets if they were to win promotion to the Premiership. On 9th April 2006, the News of the World suggested that Davenport was a target for Celtic manager Gordon Strachan who had worked with him at Coventry.

On 31st May 2006, Spurs announced that they would be seeking to sell Davenport, and it is expected that they would seek a fee of around £1million for him. Both the News of the World and The People reported that Watford manager Adrian Boothroyd would be seeking to bring Davenport to Vicarage Road for the Hornets' Premiership campaign.

On 16th June 2006, the Star and the Express both reported that Wolves and Birmingham were locked in a transfer tug-of-war over Spurs £1.5m-rated centre-back Calum Davenport although the Daily Mail speculated two days previously that Celtic and Charlton were also competing with Birmingham for Davenport. On 30th June 2006, The Sun reported that West Brom had made a £1.3m bid for Davenport. The same paper speculated in December 2006 that Davenport would be a makeweight in the transfer to West Brom defender Curtis Davis to Spurs for £5m. The Guardian speculated on 5th January 2007 that Davenport and teammate Wayne Routledge would be offered to Watford in return for highly rated Ashley Young.

On 18th January2007, Calum signed for West Ham United who were spending their new Icelandic owners' money in an attempt to avoid relegation. Other Janaury 2007 signings include Luis Boa Morte (Fulham), Nigel Quashie (West Brom), Lucas Neill (Blackburn) and Matthew Upson (Birmingham)

Reports in July/August 2007 suggested that Davenport might be rejoining City either on loan or as a permanent transfer with the Canaries needing another central defender for the new season. The 24-year-old is likely to be on the sidelines at Upton Park this season, where manager Alan Curbishley has half a dozen central defenders to choose from. He was linked on 12th August 2007 with a switch to Ipswich by the Sunday People but any move to East Anglia was dismissed by his agent two days later.

Davenport joined Watford on 18 January on loan from West Ham United with view to a permanent deal. He had made just 6 appearances for the Hammers since signing for them from Tottenham exactly one year previously. Davenport made his debut for the Hornets on 19 January in a 1-1 draw at home to Charlton but was stretchered off after fracturing a bone in his neck when teammate Darius Henderson landed on him. His injury meant that the loan was cancelled.
