National League side Dagenham & Redbridge fell to a narrow 1-0 home defeat to League Two strugglers Salford City in the FA Cup First Round.
The visitors struck inside three minutes through Jordan Turnbull’s powerful header from Liam Shephard’s corner in the final tie of the weekend.
In Saturday’s action, Charlton Athletic eventually made their superiority count to ease into the next round with a 4-0 victory against Havant & Waterlooville
Josh Davison broke the deadlock against the non-league side in the 72nd minute before Jayden Stockley made it two from the penalty spot four minutes later.
Stockley then made sure of the result with a poke home with five minutes remaining before youngster Mason Burstow added a fourth in the 90th minute.
AFC Wimbledon booked their place in the next round after scraping a 1-0 win against sixth-tier Guiseley at Plough Lane.
Three divisions separated the two sides but the visitors more than matched their hosts and were unlucky to go behind courtesy of Ollie Palmer’s strike just before the break.
Wimbledon have now progressed to the Second Round in nine of the last 12 seasons, but chaotic defending and disjointed forward play sent the Dons faithful home far from happy.
Meanwhile, Leyton Orient edged into the next round with a 1-0 home win but had to work hard throughout to overcome plucky National League South opponents Ebbsfleet.
The deciding goal was scored by Aaron Drinan, who put the O’s ahead in the 24th minute after a sterile opening period that had produced little in the way of concern for either keeper.
Elsewhere, Will Randall’s second-half winner secured Sutton United a place in the Second Round with a hard-fought 1-0 victory at Southern League Premier South side Hayes & Yeading.
Randall struck from the edge of the box with 19 minutes left after good work from substitute Donovan Wilson.

There was no cup giant killing for Bromley though, who lost 3-0 at League One side Rotherham United.
The contest was effectively ended just prior to the break with Ben Wiles and Freddie Ladapo striking in quick succession.
Bromley’s task of getting back into the game was dealt a further blow when one of their half-time substitutes, Haji Mnoga, was given a straight red card for a wild tackle on Chiedozie Ogbene before Will Grigg rounded off the scoring with 10 minutes left to play.
And finally, in-form non-league side Harrow Borough fell to a narrow 1-0 defeat away to League One side Portsmouth
Marcus Harness scored the only goal of the game in the 28th minute as Pompey were forced to scrap against the minnows.
