The Doonhamers host Premiership outfit Hibernian at Palmerston Park in their televised Scottish Cup tie.
Shields played a starring role for Queens in their history making 3-2 victory over Championship leaders Hearts last Saturday.
The ex-Aldershot attacker bagged himself a sublime first-half brace and his cross was bundled over the line by Jambos’ midfielder Andy Irving, which sealed the three points for the Doonhamers, their first victory over the Tynecastle outfit since 1963.
Speaking after the Hearts victory, Shields said: “We went there as massive underdogs but right from the start we were at it. I actually wasn’t aware that the club hadn’t beaten Hearts in nearly 60 years so to break that streak in this manner was fantastic. I thought everybody was brilliant.
“We had to come out after two previous losses against Alloa and Morton, there was no point in us sitting back. We pressed them and got our reward for that.
“We managed to get in behind them a few times and I used my pace to our advantage. First half I thought we were brilliant and then we defended well at the end.
He added: “My second goal was a brilliant one. I saw the keeper off his line and decided to give it a go. Sometimes they go miles over the bar but thankfully it went in. I’ll take the assist for the winner too!
“The win has pushed us right back up with the play-off hunting teams. We’ve got five league matches left and four of them are against our play-off rivals.”
Now Shields – who is Queens’ top goalscorer with ten strikes in all competitions this season – has his sights set on another side from the capital, Jack Ross’ Hibees, and is confident the Dumfries men can pull off a cup shock.
He said: “We need to take what we did at Tynecastle into our cup match with Hibernian. Who says we can’t do the same again?
“It’ll be a tough game on Monday night but we’ll go into it with the same attitude as we did against Hearts and try to get a result.”
Another player who played a vital role against Hearts was on-loan midfielder Ciaran Dickson. The Rangers youngster made his second start – his first only lasted 20 minutes against Arbroath last month before being substituted – and didn’t look out of place one bit.
Dickson hopes he can keep his place in the starting line-up for Monday’s glamour cup tie.
He said: “I thought the whole team were fantastic, we came here with a game plan and managed to pull it off. We have a target of getting into the promotion play-offs and this result gives us a chance.
“I was very disappointed to have come off early against Arbroath on my debut but the gaffer said it was a tactical decision change. We went on to win that match. I’m a team player so was happy with the outcome for the team.
“I’ve worked hard to get back into the starting team, hopefully I can keep starting and gaining more experiences like this.”
The Doonhamers will be without on-loan winger Dapo Mebude after he was hit with a four-match ban, with a further two matches suspended until the end of the season.
The 19-year-old – along with four of his Rangers teammates including Annan goalkeeper Brian Kinnear – was caught by police at an illegal gathering and breaching coronavirus regulations in February.
Queens manager Allan Johnston also stated that Isaiah Jones and Dan Pybus could return to training this week.
