Hull manager Steve Bruce remains convinced that his side will be promoted to the Premier League despite the 2-0 defeat at Barnsley.
The Tigers have seen a seven-point lead over third-placed Watford cut to just a solitary point ahead of next weekend's final round of fixtures, with champions Cardiff visiting the KC Stadium and the Hornets hosting Leeds.
However Bruce has backed his side to bounce back after goals from Jacob Mellis and Chris O'Grady clinched victory for the Tykes at Oakwell.
"The reason why we've got ourselves in this position is we've played badly before and responded," he said.
"It's a big, huge week and I'm confident we'll respond in the right way.
"Thankfully, it's still in our hands but we certainly need to perform to a level which we haven't seen today.
"You look at whoever you play and there's never an easy game to play. What you have to do is get to a level of performance, consistently, and we've been able to do that throughout the year.
"Over the last couple of performances we haven't been able to get there but I'm confident we'll do it next week."
Jimmy Smith put the O's ahead early on but Kirk Millar equalised for the visitors shortly after half-time.
Only 10 minutes had been played when Smith raced into the penalty area to meet a deft flick by Charlie MacDonald before sending his first-time lob over advancing goalkeeper Dean Bouzanis from 15 yards.
However, the Latics had already forged two openings by then with Korey Smith and Lee Croft both missing out with shots that only narrowly cleared the target.
The second half was just 50 seconds old when Oldham got themselves back on level terms.
The home defence failed to deal with a cross by Cristian Montano and the ball dropped into the path of Millar who applied the finishing touch, with his shot rolling over the line off the inside of the right-hand post.
With five minutes remaining substitute Lee Cook picked out Dean Cox with a superb cross-field pass but the O's midfielder squandered the opportunity of taking all three points for his side when he crashed his shot against the upright from eight yards out.
Oldham introduced 16-year-old Jack Truelove for his first taste of league football while 18-year-old Harry Lee made his league bow for the O's from the bench.
