Sunderland are still in pain after their disallowed 'winner' against Aston Villa, according to Kenwyne Jones.
The Black Cats were held to a 1-1 draw with Villa at the Stadium of Light on Saturday, but Roy Keane's side thought they had netted all three points when Danny Collins headed home in injury time.
However, referee Steve Bennett disallowed the goal for a perceived foul on Villa goalkeeper Scott Carson and Sunderland remain adamant that the effort should have stood.
Jones, though, believes his team-mates should take the sense of injustice into their next Premier League game against Reading at the Madejski Stadium as they look to secure their first away win of the season.
"It hurts when something like that happens," Jones told the Daily Star.
"We're still bitterly disappointed and upset and maybe we should stay angry when we go to Reading."
Collins has also admitted that he is still frustrated by Bennett's decision to chalk off his late goal.
"It's gut wrenching because there was nothing wrong with the goal," Collins added.
"We've scored a few late on this season and I was convinced I had got another one."
