After the incident at Vitality Stadium which halted play in the second half of the contest, the Hatters had confirmed Lockyer was “responsive” before being taken to hospital and in a “stable” condition.

An update from the club read: “Tom is still undergoing tests and scans, and is awaiting the results before the next steps for his recovery are determined.”

The statement on the club's official website added: “We understand that supporters are concerned for him and that there is widespread media interest in his condition.

“We are unable to provide a running commentary on his situation, and request that all media please wait for any updates to be released via the club’s official channels when the time is right.

“We all want the very best for Tom, his partner Taylor and the whole Lockyer family, and politely ask that his and their privacy is respected at this difficult time.”

Paramedics and staff, including Luton manager Rob Edwards, immediately sprinted to Lockyer’s aid when he appeared to collapse near midfield in the second half of what had been a 1-1 draw.

Players left the pitch as the 29-year-old Wales defender was being treated but returned to applaud the crowd after the Premier League announced the match had been abandoned, with the clock paused in the 65th minute.

Lockyer had surgery to correct an atrial fibrillation in June after collapsing during Luton’s EFL Championship play-off final win against Coventry.

He returned to action for the start of the new season and had made 15 appearances so far in all competitions before the Bournemouth match.
