24-year-old Bavalan Pathmanathan was rushed by air ambulance to hospital after the incident but later died of his injuries.
Pathmanathan was batting for Manipay Parish Sports Club in the British Tamil League on Sunday.
A teammate, who was batting with Pathmanathan at the time, told the Colombo Mirror:
"When he received the hit I asked from the other end if he is alright. He gave a thumb-up and nodded to indicate he was alright, while pressing his chest.
"He took a couple of steps behind the stumps and collapsed.
"He was such a talented and composed cricketer and a darling friend of all of us. Every one of us is going through terrible pain as a result of this terrible loss."
