Harrison Reed scored his first ever FA Cup goal as Fulham staged a second-half comeback to beat Stoke City and reach the fifth round.
The Championship side took the lead in the 19th minute with an emphatic finish from midfielder Jun-Ho Bae.
But Fulham roared back after the break and ended a run of three consecutive defeats across all competitions thanks to goals from Kevin and Reed, who struck the winner with six minutes left after a mistake by Stoke keeper Tommy Simkin.
Both Potters boss Mark Robins and his Fulham counterpart Marco Silva made a number of changes to their sides after league fixtures in midweek.
There were five for Stoke, the 2011 FA Cup finalists but winless in six games since defeating Coventry City in the previous round.
Alex Iwobi, making his 100th Fulham appearance, was the only survivor from the defeat at Manchester City as January signing Oscar Bobb was handed a first start.
In only the second FA Cup meeting between the two clubs, Stoke had the game’s first effort when winger Sorba Thomas connected crisply with a half-volley from outside the box to force a save from Benjamin Lecomte.
And they made the breakthrough when South Korean Bae received the ball from Eric Bocat and rifled home from inside the area after a sweeping move.
Keeper Simkin produced two wonderful saves to deny Kevin before the break, while Iwobi also headed wide from less than six yards out.
The hosts almost doubled their lead seven minutes into the second-half when Lamine Cisse – their match-winner in round three against Coventry – saw his curling effort tipped on to the post by Lecomte.
But Fulham responded to that wake-up call with a 55th-minute leveller as Brazilian winger Kevin surged into the penalty area and drilled a low effort past Simkin.
The Premier League side then began to flex their muscles and brought on Raul Jimenez and Emile Smith Rowe as they pushed for a winner.
The decisive moment arrived when Simkin tried to play out to a team-mate from inside his box and Reed pounced to win the ball and calmly slot home his second goal this season, but first in the FA Cup.
