India's HS Prannoy battled pain in his ribs and a potential dislocation on his left shoulder to stun Indonesia's world number seven Jonathan Christie in the first round of the Toyota Thailand Open Super 1000 badminton tournament on Wednesday. Prannoy recovered from a game down to beat sixth seed Christie 18-21 21-16 23-21 in a match that lasted an hour and 15 minutes.

Prannoy had been diagnosed with Covid-19 two months ago and said after the match that the pain in his rib cage was due to a muscle strain caused by coughing continuously. The shoulder pain came from a fall during a rally that gave Christie match point. However, he fought back from that position and went all the way to win the match.
