Chelsea have posted a video of winger Callum Hudson-Odoi completing a cycling workout after his positive coronavirus test last week.
A shirtless Hudson-Odoi can be seen cycling to music before smiling at the camera in a 16-second clip posted on Tuesday.
Chelsea added a comment praising the 19-year-old, saying he was looking strong.
Hudson-Odoi became the first Premier League player to test positive for COVID-19 in a diagnosis confirmed on Friday, having first displayed cold-like symptoms on March 9.
The entire Chelsea squad, coaching staff and several backroom staff self-isolated as a result.
Hudson-Odoi tweeted a video promptly after his diagnosis saying he had "recovered" and was following health guidelines regarding his isolation.
He added: "Thank you for all your good wishes, as I said in the video I'm feeling good and hope to see you all soon!!"
The coronavirus pandemic has brought a complete halt to major sport, including football in the top European leagues.
