More perspective here from a Cricinfo piece.It sounded horrific but it had to happen sooner or later.
Hope there's only superficial damage and best wishes to him for a speedy recovery.
"I'm really lucky to be here now and speaking to you today," he (Fletcher) said. "The doctors said I pretty much dodged a bullet. A few inches to the left or right and it could have been a completely different story. If it had hit the temple or straight in the face then…. I don't really want to think about what may have happened."
Fletcher warns that, in training, bowlers are already reluctant to bowl at batsmen practising their T20 skills.
"I think it'll happen again," he said. "Most bowlers - certainly at Notts - in the nets tend to go away and do target practice on the side in one-day and T20, just because balls are coming back at a speed you can't react to. You get hit all over your body. I certainly think the chances are it will happen again."
With bats better, batsmen seemingly more powerful and the aggression of the game having undergone a transformation since the introduction of T20, it seems inevitable that, sooner or later, we're going to see a bowler killed by a return hit (this is G Dobell writing)
