Garry Ringrose, Hugo Keenan, Iain Henderson and Oli Jager are in contention for Ireland’s Guinness Six Nations clash with England after training on Tuesday.
Leinster centre Ringrose is yet to feature in this year’s championship because of a shoulder injury.
Full-back Keenan and lock Henderson missed the round-three win over Wales due to a knee issue and a dislocated toe respectively.
Munster prop Jager made his Test debut as a replacement in that 31-7 success on February 24 before sustaining a knee problem.
Grand Slam-chasing Ireland, who play at Twickenham on Saturday before completing their campaign at home to Scotland seven days later, reported a clean bill of health ahead of holding a more physical training session on Wednesday.
“We were all on the field today, it was great,” scrum coach John Fogarty told reporters.
“Garry and Hugo, Hendy, all trained today, Oli as well.

“So, yeah, it’s such an important day for us to be on the field. A healthy squad training today is important for selection and it was great they were all on the field.”
Ciaran Frawley deputised for Keenan against Wales and marked his first international start with one of four tries for Andy Farrell’s side.
Asked about the progress of Ireland’s first-choice number 15, Fogarty said: “Well, he trained today.
“Again, they are on the road to recovery, training on the field today live was important for them. We’ll see how they got through the session.
“We’ve another session tomorrow, which is the most physical session of the week where we’ll properly test our plan and the players so we’ll see how he gets through tomorrow and then Andy will select his side.
“(Today) it’s full speed, there’s no huge contact in it, it’s kind of a coaching day.
“Monday is forming a plan, Tuesday we put it on the field and we’ll see the timings of our launch plays and how our defence works, and tomorrow we’ll test that full contact.
“We want to get as live as possible, ready for what’s going to be a huge test in Twickenham.”
'World-class' Scotland will provide Wallabies' sternest test – Skelton
Australia will face their sternest test to date when they continue their autumn tour against a "world-class" Scotland team at Murrayfield on Sunday.
That is the view of forward Will Skelton, who believes the Wallabies' victories in England and Wales have brought a new energy and confidence to their camp.
Having crashed out in the pool stage at last year's World Cup in France before finishing last in the Rugby Championship, Australia have looked a team reborn in recent weeks.
A first victory at Twickenham since 2015 and a 52-20 rout of Wales – their biggest-ever away win in matches between the teams – have made it an excellent tour to date for Joe Schmidt's side.
But La Rochelle lock Skelton feels their toughest assignment is to come this week, saying: "We've won two games, we're very aware of that.
"The Test against Scotland is going to be the hardest one yet. We're excited about this weekend and we're looking forward to ripping into it.
"Physically they're up there with the top five in the world. I think set-piece wise they're really strong.
"You've got a guy like Finn Russell who's a maestro at the back there. I think it's going be a close one and we'll be up for it.
"There's some class players in the Scottish team and, when they're at it they're world-class, so we're going to have to be on top of our game."
Wales must 'show courage and front up' against South Africa, says Gatland
Warren Gatland has urged Wales to "show real courage and front up" in their final Autumn Nations clash against South Africa.
Gatland's side bring the curtain down on a disappointing year when they welcome the reigning world champions to the Principality Stadium on Saturday.
Wales have lost an unprecedented 11 straight Tests, and could go an entire calendar year without tasting success for the first time since 1937.
Gatland has made four changes from last weekend's 52-20 defeat to Australia, with Sam Costelow, Rio Dyer, Christ Tshiunza and Taine Plumtree all coming into the starting XV.
Gareth Anscombe, Aaron Wainwright and Cameron Winnett drop out of the squad, while Adam Beard misses out through injury.
And Gatland wants his players to demonstrate fighting spirit against the Springboks.
"Last week's result hurts, and we are just as disappointed by it as the fans," he told reporters during his pre-match press conference.
"Our focus now is on training and preparing well for our final game of this Autumn Nations Series.
"There were good elements that we can definitely build on going into Saturday, but we have to improve our accuracy.
"We know what a quality side South Africa are and the physicality they bring. This week, we need to show real courage and front up against the world champions."
'Playing for England is the Mecca' according to Itoje amid global breakaway talk
Maro Itoje has reaffirmed his commitment to England amid talks of a proposed global breakaway league.
Steve Borthwick’s side are looking to end their five-match losing run when they face Japan in their final match of the autumn series on Sunday.
But there is fear that Borthwick could lose many of his players to the new league that reportedly are offering 40 £1m-a-season contracts for marquee players and more periods of rests for the players.
The Rugby Football Union (RFU) only select players for the national team from English clubs, meaning any player joining the breakaway league would jeopardise their Test career.
But Itoje has insisted that playing for England is the pinnacle for him and his teammates.
"I don't really know any of the details of it as yet, but wearing this rose is extremely important to me and my teammates," said Itoje.
"Playing for England is the Mecca."
