Wetherall played in the game when against arch-rivals Manchester United in 1997 when Roy Keane badly injured his knee. Keane later took revenge on Alf Inge Haaland during a Manchester derby and said to him as he lay on the ground: "And don't ever stand over me again sneering about fake injuries, and tell your pal (David) Wetherall there's some for him as well.
David Wetherall will always be remembered fondly by Leeds fans in particular because he twiced scored against Manchester United, first in 1994 in a 2–1 win, and then the only goal in 1–0 in 1997.
He played more than 200 league games for Leeds scoring 12 goals. In total he appeared in 250 games.
The 2000–01 season started early for Bradford after chairman Geoffrey Richmond decided to enter the Intertoto Cup. Wetherall did not play in the team's first game away at FK Atlantas, and after playing in the second leg and the two third round games, he missed the semi-final with Zenit St Petersburg because of an ankle injury. City subsequently lost both legs. Wetherall started the league season but after playing all 52 league games since joining Bradford without leaving the field, Wetherall limped off before half-time during a 2–0 defeat to their nearest rivals Derby County in November 2000. Days after new manager Jim Jefferies took over, Wetherall was ruled out until the following February following a groin operation. His first game back was on 24 February 2001 as City lost 2–1 to West Ham United. His return to league action lasted just four games when he was ruled out for the rest of the season after scoring in a 2–2 draw with Newcastle United. Bradford lost their Premiership status a month later after losing 2–1 at Everton.
Wetherall's start to the 2001–02 season was hampered by a groin injury and his first full game of the campaign came on 14 September 2001 when he scored in a 5–1 Division One victory over Gillingham, which put Bradford second in the table. A groin injury again kept Wetherall out of the side for nearly five months, during which time he was linked with moves back to the Premiership at either Southampton or Manchester City, but he opted to stay at Valley Parade. He returned from injury for a reserve game in March after four months out with just over two months of the season left. He returned to the side against Burnley in a game noted for Paul Gascoigne's debut for Burnley, and scored in his next game as Bradford eased any relegation worries by defeating Crewe Alexandra 2–0. He played in the club's final seven games and was named club captain for the following season after Stuart McCall left the club.
Wetherall was one of 19 senior first-team players to be laid off by chairman Geoffrey Richmond in May 2002, after the club were put into administration and the players unpaid since April. The players then went on strike before a pre-season friendly at Hull City even though Wetherall, as the club's PFA representative denied the move would happen, before the club was saved, and players reinstated. Wetherall played in the club's opening game of the season as Bradford drew 0–0 with Wolverhampton Wanderers live on television, but was again ruled out through an injury, this time to his hip. A planned comeback was put off five weeks later, before he sought the advice of a specialist in Denmark. After sitting out another three months through injury, Wetherall made his return as a substitute against Gillingham in December 2002 but was again injured in a reserve team comeback three days later. He again returned in February 2003 against Coventry City and played 15 games during the final three months of the season.
Wetherall kept off his injury problems and played in the first 15 games of the 2003–04 season, but was ruled out for two months after suffering medial ligament damage, following a knee injury sustained during the club's 1–0 defeat to Watford. He returned on 28 December 2003 in a 1–0 victory which gave Bradford their first win in six games. His return to the defence added a second successive clean sheet. The revival in form was short-lived and despite Wetherall missing just one more game, when he sustained a calf injury, Bradford were threatened with another relegation. Wetherall scored a header against Reading in a 2–1 win and gave Bradford a "slim chance" of avoiding relegation, only for that to be confirmed two weeks later after a 3–2 defeat to Wimbledon.
Despite the club's relegation to League One and another spell in administration, Wetherall turned down a move away from Bradford City after snubbing Coventry City during the 2004 summer. In October 2004, Wetherall and fellow veteran player Dean Windass both signed year's extensions to their contracts, with Wetherall's keeping him at City until the end of the 2007–08 season. He also put his injury problems to one side for the 2004–05 season and missed just one league game – a 1–1 draw with Walsall in February when he was ruled out because of suspension ending his run of 42 consecutive games. Bradford manager Colin Todd had identified Wetherall as a key player for the season, but despite scoring four goals and striker Dean Windass' 27 goals earning him the league's top scorer's crown, Bradford could only finish 11th.
In October 2006, days after playing his 250th game for Bradford, he signed a new deal keeping him at the club until 2010 with a clause allowing him to move into a coaching role when his playing career ended or continue playing beyond 2010.
He received the first red card of his career in a 2–2 draw with Cheltenham Town on 30 December 2006 for two bookable offences.
When he took as Bradford caretaker manager Wetherall stepped down as captain and instead handed the armband to centre back partner Mark Bower. But when Stuart McCall was appointed the new manager in June 2007, Wetherall was reinstated as club captain for the 2007–08 season. On 20 February 2008 he announced the 2007–08 would be his last as a player, although Bradford City would keep his registration, and instead he would join the club's coaching staff. Bradford fans held a special day to celebrate Wetherall's career, when they took banners and wore fancy dress and laboratory coats during the club's 1–1 draw with Rotherham United on 22 March 2008. In his penultimate month as a footballer, Wetherall was also named the League Two fans' player of the month by the Professional Footballers Association. He played his final game for Bradford against Wycombe Wanderers on 3 May 2008 in a 2–1 defeat.
Wetherall returned to concentrate on his playing career after Stuart McCall was named full-time manager during the summer of 2007. Wetherall holds the UEFA B coaching licence and is due to complete his A licence during the summer of 2008, when he will return to the Bradford City coaching set up.
