The Sun reports Ed Hodge has blasted the way the players are being prepared at the club.
In a now-deleted tweet showing what appeared to be a private Instagram conversation, Hodge revealed the reason behind all of the injuries at Chelsea.
He wrote: "Most of the injuries are because the players have been loading muscles time and time again without lengthening them simultaneously... then one lunge into a tackle, or a COD too rapidly and they're injured.
"Hardly any of them do reformer Pilates or terrain work (i.e. stair sprints & hill sprints to strengthen knee ligaments).
"It's an absolute mess at the moment, bro."
Chelsea currently have 12 first team stars unavailable due to injury.
