League Two Grimsby earned an FA Cup fourth-round replay with Championship side Luton in an entertaining 2-2 draw at Kenilworth Road. After Gavan Holohan had put the Mariners ahead, Elijah Adebayo and Jordan Clark turned the game around for the Hatters. But, just one minute after Clark’s effort made it 2-1, Harry Clifton struck to deny Luton. In the closing stages, Luke Berry almost sent the Hatters through, only to slam a volley into keeper Max Crocombe’s midriff, meaning both sides will have to do it again next month. Striker Sam Bell seized his chance to impress with a double in Bristol City’s 3-0 victory over West Brom at Ashton Gate. Promoted to the starting line-up in place of £9m Bournemouth signing Antoine Semenyo, the 20-year-old academy product opened the scoring after 12 minutes with an exquisite right-footed curling finish from inside the box after Albion failed to clear a corner. It was 2-0 after 28 minutes, Mark Sykes breaking on to a Nahki Wells through-ball and crossing low for Alex Scott to slot in from close range. Bell, son of former City left-back Micky Bell who now works as a coach in the club’s academy, was on target again three minutes after the break, cleverly controlling a George Tanner cross from the right before lifting his shot over advancing goalkeeper David Button. Albion were run ragged at times and when they did attack with menace could not find a finish to reward their massed ranks of travelling fans. Jordan James struck in stoppage time as Birmingham snatched a dramatic 2-2 draw at Blackburn. Rovers looked to be heading through to the fifth round for the first time since 2017 after recovering from conceding Reda Khadra’s early opener thanks to Bradley Dack’s close-range finish and a precise Joe Rankin-Costello strike. But 18-year-old James, who had been on the pitch for barely two minutes, scored his first of the campaign by coolly converting a cutback to send the almost 4,000-strong visiting support wild and earn Blues a replay next week. Romain Perraud scored twice to seal Southampton’s place in the fifth round with a 2-1 win over Mick McCarthy’s Blackpool at St Mary’s. The Seasiders, languishing in the bottom two of the Championship, held their own in the first half against their Premier League opposition in what was new boss McCarthy’s first match in charge. But they were behind at the break after Perraud scored directly from a free-kick, and the French full-back then extended his side’s advantage midway through the second half before Charlie Patino pulled a goal back. The result ensures Southampton are one win away from reaching their fourth FA Cup quarter-final stage in six seasons. Ipswich and Burnley will have to meet again after drawing 0-0 at Portman Road. Nathan Tella and Jay Rodriguez both came close as the visitors improved after a poor first half, but keeper Vaclav Hladky kept them out. Sheffield Wednesday and Fleetwood also face a replay after the League One rivals drew 1-1 at Hillsborough. Promise Omochere gave the visitors the lead early in the second period, but Wednesday drew level when Josh Earl was credited with an own goal.
