According to HindustanTimes:
IAF pilot Wing Commander Abhinandan Varthaman suffered an injury in his lower spine when he ejected from his MiG-21 fighter jet last week after an aerial engagement with an F-16 that had transgressed into Indian air space, news agency ANI quoted sources as saying on Sunday.
The MRI scans revealed that though no bugs had been found on the IAF pilot, there were signs of two injuries. While one injury was on his lower spine when he ejected from his plane, the other injury was on a rib, news agency ANI quoted sources as saying. The second injury was possibly suffered when he was assaulted by some locals when he parachuted into Pakistan occupied Kashmir (PoK) after his plane was shot down.
The agency also reported that Wing Commander Abhinandan will undergo some more check ups and treatment at the Research and Referral Hospital in Delhi Cantonment.
Wing Commander Abhinandan Varthaman was repatriated to India on Friday after spending more than 50 hours in the custody after the Pakistan Army after he ejected out of his fighter jet over Pakistani territory when his MiG-21 was shot down.
