“I don’t know if he’s had this type of injury before but with his age, it is going to be a big issue. If it is a grade one or two, he may need to rest for the next six weeks to two months," he said as quoted by Times LIVE.
“Anything up to grade four will need an operation because they must stitch the tendon to facilitate the healing process. There you are looking at up to four to six months, including rehabilitation. If it's grade one or two, it will be six weeks to two months because they will need to rest the leg for a particular period in the moon boot to keep the fibres together.
“After the moon boot, he will get sauna while doing upper body exercises and if they are happy with his progress, he must start jogging and running slowly to build up. That is two months minimum. If it needs an operation, he is going to be out for three to four months.
“It is a serious injury because the tendon supports the ankle from behind and if it goes off it is a serious problem. If it is a complete tear, we are looking at about four to six months and that is the worst-case scenario," Mogoru concluded.
