Nelsen should continue to play in the FA Cup, a competition he twice bowed out of at the semifinal stage with Blackburn, and Tottenham's win today sets up a home quarter-final against Premier League strugglers Bolton next weekend.
In the league, Tottenham's title challenge has faded in the last fortnight after losing 5-2 to Arsenal in the north London derby and going down 3-1 to second-place Manchester United. With 11 games left, Spurs will now be determined to consolidate their position in the top four and ensure a return to the European Champions League next season.
Arsenal are four points back in fourth place while Chelsea are a further three back, ensuring a hectic chase for the two Champions League spots available behind the two Manchester clubs.
With every point vital and Dawson injured, Nelsen's acquisition is looking a shrewd one. While his only Premier League minutes came in the dying moments of a 5-0 win over Newcastle, Nelsen anchored the Spurs' defence in the two games against Stevenage.
His performance in the 0-0 draw at Stevenage drew praise and, although Nelsen conceded a third minute penalty which gave the minnows a shock lead in the replay, the 34-year-old's experience should prove crucial in the last two months of the season.
