O’Neill came on at half-time in place on Bobby Grant, and made an instant impression scoring shortly after Bradley Dack had given Rovers the lead.
The 19-year-old – who is on loan from Premier League side Burnley – was delighted with his side’s spirit, and scoring against his parent clubs closest rivals
“I am over the moon,” said O’Neill.
“I am absolutely buzzing, not just for myself scoring my first goal for the club, but also buzzing for the team because we came here with a game plan.
“All the hard work has paid off. We leave tonight with a very good point.
“We came here on the back of a great 2-0 home win against Oxford United, and we’ve played a good Blackburn side, who are looking to go back up again. We have put on a great performance.
“Being on-loan from Burnley and scoring at Ewood Park is a very good feeling. I am just pleased we got something out of the match.”
The Australian was introduced at the break, with another substitute Wes Burns also scoring, showing the options the club have from the bench.
“It shows that we have strength in depth,” added O’Neill
“The gaffer always tells us that it’s not just the players who are starting; it’s the players on the bench who will come on and make an impact and that is what happened tonight.
“We looked very good tonight. I felt Blackburn were tiring towards the end and that just credits what work we do as team, and how fit we are and how we can always nick a point, or even three points.
“Unfortunately tonight that wasn’t the case, but it was a close one and we are happy with the point.”
Uwe Rosler’s men now have six days before their trip to National League North side Chorley in the Emirates FA Cup, and the loanee is now looking forward to another local derby.
“The lads are really looking forward to the game.
“We know it is going to be a tough match but we need to prepare right, and get through to the next round of the competition.”
