Scunthorpe United manager Nigel Adkins bemoaned his side's defensive display after they had to rely on a last minute equaliser to keep their unbeaten run alive.
A goal deep into stoppage time by League One's top scorer Billy Sharp kept the Iron's 17-match unbeaten run alive as they secured a 2-2 draw at Leyton Orient.
"We've finished with 11 men and scored two goals but I'm disappointed with the goals we conceded," said Adkins.
"We haven't won here for ten years and before that our last win was in 1962, so traditionally it's been a difficult place for Scunthorpe to come to.
"We could have scored several goals in the second half but their goalkeeper was magnificent and it just never happened."
