Manchester United stars Anthony Martial and Jesse Lingard both arrived for training as usual on Friday morning but left only 15 minutes later, MySportDab reports.
It was a short visit to Carrington for the pair, who are now doubts to play against Wolves in the FA Cup third round match.
The is a huge blow for Manchester United fans, with Ole Gunnar Solskjaer now revealing that a sickness bug is affecting the squad.
It is yet to be confirmed if Lingard and Martial – who both played on New Year day Vs Arsenal, are suffering from the illness.
Speaking to reporters ahead of the weekend, Solskjaer said: ‘There are a couple of problems, not exactly problems but illnesses and colds, which is normal at this point.
“Paul is not available for the game,” Solskjaer added.
“Tuanzebe, Bailly, Fosu-Mensah are almost fit but won’t be available for this. Rojo also isn’t ready for this.
‘I hope most players wake up tomorrow and feel OK. Today we will have a training session also.’
Not long after Coach Ole Gunnar Solskjaer’s press conference the United players arrived for training, only for Lingard and Martial to leave again.
MySportDab confirms both players were pictured arriving at training, before leaving through the gates just minutes later.
Jesse Lingard came in quite early, arriving at 9:31am but he was seen leaving not long after at 9:48am.
Meanwhile, Martial arrived after Lingard left at around 9:55am but was already back in his Range Rover and left for home at 10:10am.
