Former Commonwealth Games champion shuttler Parupalli Kashyap says he will have to “reassess his training” after being ruled out for six weeks due to a recent calf muscle injury.

A former world No 6, Kashyap sustained a grade 1 calf muscle pull during the All India Senior Ranking tournament in Hyderabad (December 24-30) last month.

“I played Hyderabad Open, and I got injured in the first round, just when I was feeling really good but it seems I wasn’t good enough for the match,” a disappointed Kashyap told PTI.

“I am not sure why it happened, probably it is the age...now I think I have to reassess what is happening in training.

“I am thinking I am fit but probably I am not. my stamina for the calf muscles was not enough, the strength endurance for the calf muscle to last the entire match was not enough,” he added.

Kashyap, 35, has been troubled by frequent injuries and fitness issues ever since his Commonwealth Games gold in 2014.

After enduring another tough year, the shuttler was looking for good outings at the two All India senior ranking tournaments at Chennai and Hyderabad.

The injury means Kashyap will not be able to participate in the three events in the country, starting with the India Open Super 500.

“It is a grade 1 pull, so six weeks I will be out of action, three weeks to get back on court, three to get match fitness, so I am targeting March,” he said.
