O'Neill sticking with Black Cats
Leeds boss Neil Warnock is expected to name an unchanged squad for Tuesday night's Championship clash with Leicester at Elland Road.
The Whites recorded their first league win in eight matches against leaders Crystal Palace on Saturday and Warnock will be reluctant to make too many changes.
Loanees Alan Tate and Jerome Thomas both impressed from the start on their Elland Row bow and are expected to retain their places.
Luke Varney serves the second of his three-match suspension while Jason Pearce also sits out the final game of his ban.
Midfielder David Norris also returned to the starting XI against the Eagles and is likely to continue in the middle. Aidan White and Michael Brown are likely to take their place on the bench again.
Returning striker Ross McCormack is still waiting to make his first start since recovering from an ankle injury and could partner top scorer Luciano Becchio if El-Hadji Diouf is rested.
Rodolph Austin remains sidelined with a cracked ankle bone while Davide Somma is not yet able to resume full training.
Leicester boss Nigel Pearson also looks like picking from an unchanged squad for the game.
Leading scorer David Nugent missed the 2-0 victory over Sheffield Wednesday on Saturday with a neck injury that Pearson last week predicted would keep the striker out for "the next couple of games".
Jamie Vardy partnered Martyn Waghorn in attack at Hillsborough, though Marko Futacs is also available should Pearson opt to change things around.
Anthony Knockaert will also be pushing for a recall, but the Frenchman will be hard-pressed to displace Ben Marshall whose late goal confirmed victory over the Owls.
Left-back Paul Konchesky is available again following a hamstring strain, leaving centre-half Sean St. Ledger (hamstring) as Leicester's only other injury absentee.
Wearside was buzzing on Saturday evening, hours after the Black Cats' 4-2 home defeat by West Brom, as rumours of the Ulsterman's departure spread like wildfire with the help of Twitter.
But O'Neill admitted he was as surprised as anyone as club officials spent the evening denying the speculation.
The 60-year-old, who will celebrate 12 months at the Stadium of Light next month, said: "Yes, it was a bit of a surprise, really. Nothing probably should surprise me in the game, but yes.
"There was nothing in it. Anybody can tweet these days. I think it happened a couple of years ago as well, something like that, a similar sort of thing.
"But that's the nature of it. But no, I was pretty surprised."
It was not the first time talk of O'Neill's impending demise had swept the city in recent weeks, but as he prepared his players for tomorrow night's Barclays Premier League clash with QPR, the manager was adamant that it was business as usual.
Asked if he was planning to go anywhere, he said emphatically: "Absolutely not."
The speculation has come amid a sequence of poor results for Sunderland, where less than a year ago fans had hailed the arrival of O'Neill as their long-coveted manager.
A battling 2-1 victory over Blackburn at the Stadium of Light proved the perfect start, and a run of seven wins and a draw in his first 10 league games - his only defeats came, narrowly, at Tottenham and Chelsea - further enhanced his reputation with fans delighted at his arrival.
However, the last 26 league games have brought just four victories - the last three of them against sides reduced to 10 men - and yielded only 24 points from a possible 78.
O'Neill acknowledges the need for an improvement on those statistics, starting with tomorrow night's game, although he is refusing to classify it as a must-win affair.
He said: "We have got a fairly lengthy time to go. It's an important game, it's every bit as important as the game against West Bromwich Albion, and the one against Fulham, of course.
"It would be nice to win the match. I wouldn't say it's going to define everything, but all games are important."
The Black Cats' hopes of securing a morale-boosting victory are not being helped by injuries to defender John O'Shea and midfielder Lee Cattermole, both of whom are fighting against the clock to recover.
In addition, they will be the first side to encounter Rangers under the leadership of new manager Harry Redknapp, and O'Neill is well aware of the galvanising effect the former Tottenham manager's arrival could have on an expensively-assembled squad.
He said: "We are not capable of treating anybody lightly, far from it. We are not good enough to do that at all.
"But in many aspects with him coming in, it's a game for us that we know now the players' concentration has to be absolutely at its height.
"We have just got to go and try to create some chances against a side that looked as if it had played very well against Manchester United, so they will come, even though they haven't won yet, with plenty of confidence themselves.
"From all accounts - and I have watched a good deal of the game against Manchester United at Old Trafford - they played very well, took the lead and played very well up until the equalising goal.
"Manchester United, of course, are a very fine side, but in terms of performance, they will have gained a great deal from that."
