But Wrexham's high-profile ambitions of making the top-flight will have to wait after they failed to make the playoffs.
Instead, the fours teams left with a chance of making the Premier League next season through the playoffs are Millwall, Hull City, Southampton and Middlesbrough.
Ipswich, who were relegated last season, secured their immediate return to the Premier League by beating Queens Park Rangers 3-0.
Wrexham, owned by Hollywood celebrities Ryan Reynolds and Rob Mac, missed out on a place in the playoffs with their 2-2 home draw with Middlesbrough.
Wrexham had started the day in sixth place -- the last of the four playoff places -- ahead of Hull City on goal difference, but their draw proved not enough when Hull came from a goal down to beat Norwich 2-1 to leapfrog the Welsh side into sixth.
Hull's winner, scored by their two-goal hero Oli McBurnie in the 67th minute, appeared to be scored from an offside position, but there are no video reviews in England's Football League, unlike the Premier League.
It ends Wrexham's run of three straight promotions under their Hollywood owners — a streak that began by them getting out of the fifth tier in the 2022-23 season and has been documented in the globally popular, Emmy Award-winning "Welcome to Wrexham" series.
Coventry ended their triumphant season by deciding to wear their infamously awful chocolate 1978 away strip, voted the most appalling ever, but it didn't stop them smashing Watford 4-0, with a hat-trick from Ellis Simms.
The Sky Blues finished on 95 points to Ipswich's 84, Millwall's 83, Southampton and Middlesbrough's 80, and Hull's 73.
Meanwhile, an American consortium completed the purchase of Sheffield Wednesday, ending the historic English club's long takeover saga and the controversial tenure of former owner Dejphon Chansiri.
Arise Capital Partners, fronted by US businessman David Storch, takes over a club founded in 1867 that will be playing in the third tier next season after years of financial turmoil.
The acquisition was announced on the field at Wednesday's Hillsborough stadium ahead of the already-relegated team's last match of the second-tier Championship season at home to West Bromwich Albion.
Wednesday won 2-1 to end the campaign on zero points, having been deducted 18 points during the season for financial mismanagement.
