Ross Barkley scored a dramatic late equaliser as Everton salvaged a 2-2 Premier League draw against struggling Hull City at the KCOM Stadium.
Robert Snodgrass' impressive free-kick with 25 minutes remaining looked like it would be enough to give Hull a much-needed victory, but Barkley headed in to give the visitors a point from an enthralling clash.
Marshall atoned for his error by tipping Romelu Lukaku's shot onto the crossbar after the break, while Snodgrass also hit the woodwork with a free-kick at the other end before going one better with another set-piece.
But it was not enough to secure the points for Mike Phelan's side, with the recalled Barkley levelling before Everton substitute Dominic Calvert-Lewin squandered a glorious chance to win it.
The result means Hull have now won only one of their last 17 top-flight matches, but they are off the foot of the table.
Everton made a strong initial response, with Kevin Mirallas' deflected shot saved by Marshall and Coleman heading against the post from Gareth Barry's cross.
Barkley – in as one of three Everton changes – and Barry both fired just off target as the visitors continued to press.
And the leveller arrived in bizarre fashion in first-half stoppage-time when Mirallas' corner was punched into his own net by Marshall.
The Toffees almost completed the turnaround after the break as Lukaku collected Mirallas' pass and saw his deflected strike brilliantly tipped on to the bar by Marshall.
Barkley produced a tame finish after Lukaku's flick-on had helped him race clear before it was Hull's turn to strike the frame of the goal when Snodgrass' curling set-piece bounced off the bar from just outside the area.
After Harry Maguire had been fouled by Leighton Baines, Robles was unable to keep out Snodgrass' superb strike from 25 yards – his sixth league goal of the season.
Everton pushed hard for a way back into the contest and it arrived with only six minutes left on the clock – just as Hull appeared to be inching towards victory.
Barkley was poorly marked by the home defence and firmly headed in from Baines' left-wing cross, much to the relief of Ronald Koeman, though it could have been even better had Calvert-Lewin not missed the target from Coleman's last-gasp cross.
