Jonny Evans and Toby Collyer were spotted in Manchester United training on Wednesday, ahead of the club's Europa League clash with Viktoria Plzen. Evans has been absent from the last four matchday squads, last featuring in the opening game of the Ruben Amorim era at Ipswich Town.
Meanwhile, Collyer has been out of action since picking up an injury before United's 2-1 victory over Brentford on October 19.
Victor Lindelof also joined the training group after Amorim confirmed his return to training prior to Saturday's 3-2 defeat against Nottingham Forest at Old Trafford.
The Red Devils have managed to get their Europa League campaign back on track since Erik ten Hag's sacking, having started with three successive draws.
Back-to-back home victories against PAOK and Bodo/Glimt have propelled Amorim's side to 12th place in the table, leaving the top eight within reach.
However, they still need a positive result in the Czech Republic to continue climbing the ranks on the back of a disappointing Premier League result at the weekend.
This fixture comes amidst a turbulent time for United, following sporting director Dan Ashworth's shock departure after just five months.
On Sunday, there is the small matter of the Manchester derby against Manchester City at the Etihad Stadium, where Amorim will be looking to avoid a third consecutive Premier League defeat.
The team will fly to Plzen on Wednesday evening, with a full squad announcement expected in due course. A press conference featuring Amorim and Tyrell Malacia is scheduled for later this evening in the Czech Republic.
United could go as high as fourth in the Europa League table this week, although that would require several other results going in their favour.
It's safe to presume three points would at least earn passage into the top eight with FCSB and Rangers left to play.
United's latest training squad featured a full first-team roster apart from Luke Shaw, who suffered a fresh injury at Carrington earlier this month.
