Promise Omochere was on the mark for Fleetwood in their 1-1 draw at Sheffield Wednesday in round four of the FA Cup.
Former Bohemians player Omochere gave the visitors a lead early in the second period, but Wednesday drew level midway through the half when Josh Earl was credited with an own goal.
The home side, who upset Premier League Newcastle in the third round, dominated in the first half with Mallik Wilks threatening on a couple of occasions.
The striker headed wide early on and then had a shot turned away by Fleetwood goalkeeper Jay Lynch.
Wednesday's Jack Hunt also tried a shot which went wide.
Fleetwood made a bright start to the second half with Brendan Sarpong-Wiredu heading over from a good position before they took the lead.
The goal came when Danny Andrew's cross from the left was met by a diving header from Omochere in the 52nd minute.
Wilks shot wide from inside the area and then had a shot comfortably saved by Lynch.
The equaliser came in the 71st minute when Marvin Johnson's cross from the left was met by Wilks, running in, with Fleetwood's Josh Earl appearing to get the final touch before the ball went in.
Leeds avoided another FA Cup upset by winning 3-1 at Accrington Stanley to reach the fifth round for just the fourth time in 20 years.
Jack Harrison's stunning strike gave the Premier League side an interval lead and two goals in as many second-half minutes from Junior Firpo and Luis Sinisterra killed the tie.
But it was not all plain sailing for Jesse Marsch's side and Sky Bet League One side Accrington deservedly pulled one back through teenage substitute Leslie Adekoya's first senior goal.
But Leeds, dumped out of the cup by the likes of Hereford, Histon, Rochdale, Sutton, Newport and Crawley in recent years, had too much quality for their hosts and reached the last 16 for the first time in seven years.
Kelechi Iheanacho was Leicester's saviour again as the Foxes squeezed past Walsall.
The substitute's deflected strike clinched a 1-0 win to send the visitors into the fifth round and spare Youri Tielemans' blushes.
The skipper missed a second-half penalty before Iheanacho ended the Saddlers' stubborn resistance.
Iheanacho, who also scored the winner in the 1-0 third-round victory at Gillingham, now has 17 goals in 23 FA Cup appearances.
It was a slog for Leicester with Walsall edging the first half but Michael Flynn's men never seriously tested Daniel Iversen.
The League Two side can still be proud of their efforts even if Flynn was unable to add another upset to the list.
Fulham and Sunderland could not be separated in their fourth round clash at Craven Cottage with Tom Cairney's equaliser securing a 1-1 draw for the hosts.
Sunderland took the lead in the sixth minute when Jack Clarke capitalised on a defensive error to fire his side in front.
The early blow seemed to spark Fulham into life although they had to be patient, with a number of chances scuppered before Cairney cleverly created space in the box and hit a low shot into the back of the net to level matters in the 61st minute.
While neither side will have wanted to add to their already congested fixture schedule, they will now have to face each other again to decide which team will progress to the fifth round of the competition.
Romain Perraud scored twice to seal Southampton's place in the FA Cup 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.
League Two Grimsby earned a replay with Championship side Luton after a 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.
West Brom's fine league form deserted them as they were comfortably beaten 3-0 by fellow Championship side Bristol City thanks to a brace from striker Sam Bell, while Blackburn drew 2-2 with Birmingham and Burnley were held to a goalless draw by Ipswich at Portman Road.
