Wigan Athletic forward Charlie Wyke has been hospitalised after he collapsed during training.
Wyke, 28, collapsed during a session as the League One team prepared to face Cambridge United, who they drew 2-2 with on Tuesday night.
In a statement Wigan confirmed medical staff immediately attended to Wyke after he collapsed and he has since been transferred to hospital where he remains in a stable condition.
Wyke has been in conversation with his family, hospital staff and is club staff members but he will not be in contention to play in the immediate future.
In a statement Wigan Chief Executive, Mal Brannigan, said: 'First and foremost, the absolute priority for everyone associated with Wigan Athletic is Charlie's health and wellbeing and providing support to him and his family.
'As a Club, we would like to place on record our sincere appreciation to all of the staff within the NHS who, within what we know are challenging times, were excellent in their response and subsequent care for Charlie, working together with our medical team.
'Clearly this news will cause alarm, though we would politely request that the privacy of Charlie and his family is respected. At the appropriate time, we will look to provide further updates to our supporters.'
Wyke played no part in Tuesday's 2-2 draw with Cambridge United as Wigan cited illness for his absence.
The former Sunderland striker's last appearance for Wigan came in the FA Cup on November 16 against non-league side Solihull Moors.
Details and understanding as to why Wyke collapsed during a training session have not been revealed by the club as the striker is now being monitored by Wigan's medical staff and an independent consultant.
The increase in the number of players collapsing during matches and at training is of grave concern to clubs across the world.
Earlier this week Sheffield United midfielder John Fleck collapsed on the pitch during his side's Championship fixture with Reading on Tuesday night.
The Blades were leading 1-0 thanks to Jayden Bogle's 56th-minute strike when Fleck collapsed on the pitch in the second-half.
His team-mates immediately called for medical assistance and the 30-year-old received 10 minutes of urgent treatment on the pitch at the Madejski Stadium before being transported to Royal Berkshire Hospital.
After remaining conscious in hospital for around 12 hours, Fleck was released on Wednesday morning and headed back to Sheffield and will be monitored by the club closely after speaking clearly to the club, medics and his family.
On Wednesday night in the UEFA Champions League Sherrif Tiraspol witnessed disturbing scenes when winger Adama Traore went down clutching his chest.
The Mali attacker committed to a 50/50 challenge on the touchline with Real Madrid's Nacho Fernandez and when the ball went out of play Traore appeared under duress.
Traore, 26, turned to walk away from the ball, which had gone out for a throw-in, in the 77th minute when he immediately became uncomfortable, clutching his chest before slumping to the turf.
He remained breathing throughout but after a few seconds of lying on the ground in distress the Moldovan side's medics raced on to help.
Medics immediately looked to use smelling salts to activate his senses but he was not reacting strongly too them.
He was seen shaking his head in responses to questions by the medics and was eventually raised to a sitting position before being helped off the field and back to the dressing room.
The Moldovan side have yet to detail the reasons behind why Traore was suffering from chest pains.
Wyke will now take some time away from the pitch to recuperate and understand the reasons behind why he collapsed during training.
Barcelona striker Sergio Aguero is taking three months out of the game after he was diagnosed with cardiac arrhythmia having been forced off with chest pains in their 1-1 draw against Alaves last month.
Aguero insisted he was in feeling positive, tweeting: 'I am fine and in good spirits to face the recovery process.
'I want to thank everyone for so many messages of support and affection that make my heart stronger today.'
