Former India captain and coach Ravi Shastri has called the rate of injuries suffered by their fast bowlers "ridiculous".

India have suffered with maintaining the health of their pace options over the past few years, with players struggling to complete full tours.

Deepak Chahar is the latest India seamer to be sidelined, after suffering a left hamstring injury during the Indian Premier League game between Chennai Super Kings and Mumbai Indians.

Players are rehabilitated at the BCCI's National Cricket Academy, but Shastri has now questioned just how effective the team's recovery methods are, given their high turnover of problems.

"Let's put it this way: there are quite a few in the last three or four years who are permanent residents of the NCA," Shastri told ESPN's T20 Time:Out.

"Soon, they'll get a resident permit there to walk in any time they want, which is not a good thing at all. It's unreal.

"You're not playing that much cricket to be injured again and again. If you are going to come back, make sure you get fit and come once and for all because it's frustrating not just for the team, the players, the BCCI, the captains of the various franchises.

"I can understand a serious injury, but every four games when someone touches his hamstring or someone touches his groin, you start thinking what are these guys training. Some of them don't play any other cricket. It's ridiculous.

Jasprit Bumrah, Navdeep Saini, Kuldeep Sen, Mohsin Khan and Yash Dayal are among the other pace options India have seen injured to varying degrees in recent months.

Bumrah, in particular, attempted an unsuccessful comeback before conceding the need for surgery in March.
