Aaron Pierre scored a last-gasp equaliser to maintain Wanderers' unbeaten start to the new season.Former Chairboy Matt McClure looked to have caused an upset on his return to Adams Park with an early opener, but he was later sent off and the Daggers couldn't hold on his absence, with Pierre heading home from Michael Harriman's cross.
The game was barely six minutes old when Dagenham capitalised on a strong start by taking the lead through McClure, who latched on to Christian Doidge’s through-ball and finished neatly past Matt Ingram.
Sam Wood and Joe Jacobson saw efforts go wide before Janoi Donacien was just unable to convert on his debut after Liam O’Brien dropped a high ball into his path.
The chances kept coming when Garry Thompson’s near-post snapshot was saved, Wood headed wide from Sido Jombati’s inviting cross and the left-winger was inches away from reaching Garry Thompson’s delivery towards the back stick.
The lively Jodi Jones curled an effort straight at Ingram as the visitors threatened on the counter-attack, before a moment of controversy denied Dagenham a second goal just before the interval when Ayo Obileye found the net from a free-kick only to be denied by an offside flag, and after a long period of consultation between the referee and his assistant, the decision stood, leaving it 1-0 at the break.
Garry Thompson fired just over from distance moments after the restart and Stephen McGinn twice shot wide from difficult positions before Aaron Amadi-Holloway and Jason Banton were introduced from the bench in the hope of bringing Wycombe back into the game.
Banton came inches away from an immediate impact when he curled his shot just the wrong side of the post before Doidge had a rare Dagenham chance, rolling a low effort into the arms of Ingram.
There was more reason for Wanderers to believe a comeback was on the cards when the visitors were reduced to 10 men after a second yellow card was shown to McClure, allowing the hosts to throw caution to the wind with Aaron Pierre joining the attack.
McGinn forced a smart save from O’Brien after the Daggers only half cleared Sam Wood’s ball into the box, and a stoppage time free-kick from Garry Thompson threatened to test the keeper only for the wall to deflect the shot and nobody could convert the loose ball from Amadi-Holloway’s knockdown.
There was a handball shout when Sido Jombati headed Ryan Sellers’ long throw on to the raised arm of a defender, but from Michael Harriman’s resulting cross, Aaron Pierre crashed home a superb header to rescue a point with just ninety seconds left on the clock.
