Under-fire Glenn Murray came off the bench at Middlesbrough to fire Premier League Brighton into the FA Cup fifth round without knowing a great deal about it.
The striker, who was this week arrested along with his wife as part of a £1.1million tax investigation, was in the right place at the right time for defender George Friend to blast a 90th-minute clearance straight at him and look on as the ball flew into the Boro net.
It was tough luck on the Sky Bet Championship side, who had hit the post before the break through Adama Traore, although the much-changed visitors were significantly better after that to clinch a 1-0 win.
After a tame start to the second half, it was Brighton who came close to taking the lead with 58 minutes gone when Darren Randolph spilled Kayal's swerving shot from distance, but the real drama came right at the death.
George Friend got to Markus Suttner's cross marginally before Murray, but his attempted clearance cannoned back of the striker and gave Randolph no chance.
Jack Stephens marked his 24th birthday with his first goal for Southampton as they progressed to the fifth round of the FA Cup with a 1-0 home win over Watford.
The visitors' new head coach Javi Gracia was overseeing his first fixture since his arrival to succeed the sacked Marco Silva, but their form remained unconvincing as they fell to a ninth loss in 13 games.
After Stephens' early goal they played with the same lack of conviction that had contributed to Silva's dismissal, finishing fortunate not to lose by a wider scoreline to a team also struggling, and who in that same period have won only twice.
Jon Stead's goal earned Notts County a deserved replay as they came from behind to draw 1-1 with Swansea.
Luciano Narsingh's strike on the stroke of half-time put the Premier League's bottom club ahead but the underdogs responded with gusto and Stead scored the equaliser just after the hour mark.
With Swansea fighting to preserve their top flight status and Notts County battling for automatic promotion from League Two, a replay is probably what neither wanted but the two teams will do it all again at the Liberty Stadium next month.
Captain Billy Sharp sent Sheffield United into the fifth round of the FA Cup for the first time in three seasons, as they emerged 1-0 victors over Preston in a tight contest at Bramall Lane.
The Blades haven't progressed past round four since their run to the semi-finals in the 2013/14 season but Sharp's 80th-minute penalty saw them move into the next round with consecutive 1-0 wins.
