Dagenham & Redbridge clinched a five-goal thriller at Whitehawk to set up a third round clash with Everton.
Kyle Vassell and Josh Passley found the net for the Daggers, after Danny Mills had put the National League South side ahead, only for substitute Juan Cruz Gotta to head home a last-gasp equaliser.
But on-loan Charlton Athletic defender Obileye came to the visitors’ rescue on the 100-minute mark to decide an exciting replay and secure a trip to Goodison Park.

Whitehawk opened the scoring shortly after the half-hour mark when Sam Deering sent Jake Robinson away down the right flank and Mills headed in his looping cross.
Hawks boss Steve King withdrew Dean Leacock shortly before the break, introducing towering Argentinian Gotta in his place, and the move soon backfired.
Vassell collected the ball with back to goal, left his new marker behind with a sharp turn and fired into the far top corner.
The League Two side went ahead for the first time after 77 minutes when Josh Passley netted his first ever senior goal, converting Jamie Cureton’s cross.

The hosts, who earned this replay with a last-gasp leveller from Jordan Rose, piled forward in search of a winner and they found it in stoppage time when Gotta stooped to head into the bottom corner.
That forced the game into extra time and the see-saw swung once more, this time Obileye outmuscling Gotta to head home a corner of his own.
Daggers went down to 10 men shortly before the end when James Dunne was shown a second yellow card but there was no time for any more drama.
