"An MRI scan on Shahid Afridi 's knee has detected an infection," Afridi's spokesperson told the media.
Afridi has been advised at least 10-day rest by doctors. His condition will be monitored after few days to decide the course ahead, Dawn News hs reported.
Later on, the Kings painted a less gloomy picture, adding: "Shahid Afridi's MRI scan suggests slight muscular swelling around the right knee area. Further tests will clear everything."
If the prognosis proves to be accurate then Afridi will end up missing a major part of the remainder of the league matches, although he could still come back in time for the play-offs.
