James Maddison was pictured leaving Tottenham Hotspur Stadium on crutches and wearing a protective boot after featuring in Spurs' 2-0 victory over Manchester United on Saturday night.
The summer signing's first match at the north London ground since his £45 million move to Tottenham in June saw him play for 90 minutes plus nine minutes of injury time as Ange Postecoglou's side claimed the home win.
Tottenham won their first three-point tie of the campaign in style after overrunning - and in the words of Gary Neville, 'outplaying' - the lacklustre Manchester side.
Pape Matar Sarr scored his first for Tottenham two years after joining the north London team, and a woeful own goal courtesy of Lisandro Martinez pushed the side into the clear as night fell in the capital.
But supporters of the team might have been a touch concerned to see the midfielder looking to limp off as he left the stadium for the evening.
Accompanied by someone carrying his bags, the 26-year-old was focused on manouvering his crutches, worn alongside a medical boot.
Losing their new recruit could level a serious blow at Tottenham, who are still recovering from the departure of their talismanic striker, Harry Kane.
But there are reasons for Postecoglou to stay optimistic, as the midfielder is reported to have told reporters in the mixed zone that the boot and crutches were just precautionary.
The former Leicester player was involved in a painful-looking coming together in the penalty area in the dying minutes of the match, and Spurs will no doubt want to ensure any possible injury is treated as soon as possible to ensure it doesn't worsen.
Although the 2023/24 campaign is still in its opening weeks, a number of top flight clubs have already lost regular starters to injury in their opening ties.
Arsenal will be without their major defensive signing of the summer, Jurrien Timber, after the former Ajax player suffered a potential ACL injury that will require surgery and likely sideline him for at least six months.
Kevin De Bruyne is set to undergo hamstring surgery in Belgium and endure a four-month recovery period after limping off in the 23rd minute against Burnley in Manchester City's season opener, and new Chelsea captain Reece James picked up an issue with the same muscle in their 1-1 draw against Liverpool last Sunday.
Despite initially being taken off as a precaution, James was later examined more closely, and is likely to be out for a few weeks.
