Johannesburg - The Titans have sent their condolences to their coach and former England cricketer, Matthew Maynard, after the death of his son on Monday morning.
Tom Maynard, 23, a cricketer for Surrey in the English county circuit, was pronounced dead by London Ambulance Service medics following an incident at an underground station in Wimbledon, England.
The cause of his death had not yet been disclosed.
"It is with great sadness that we have learnt of the passing of Matthew and Sue's son Tom," said the Pretoria franchise's chief executive, Elize Lombard, in a statement on Monday.
"Words are truly inadequate at times like this.
"Our deepest condolences to the Maynard family - may all the prayers bring some comfort to them during this very sad time.
Northerns president Vincent Sinovich said he was "shocked" by the tragic news having recently discussed Tom's progress with his father.
The younger Maynard had promising career, and had moved counties from Glamorgan to Surrey last season.
"I was shocked to receive the tragic news of the accidental death of Tom, Matthew and Sue's son," Sinovich said.
"At the recent Cricket SA awards dinner, Matthew and I were discussing Tom coming out to South Africa this year and possibly playing some cricket in Pretoria.
"Although I never met Tom, I heard that he was a very talented young cricketer especially in the shorter format of the game.
"On behalf of Northerns cricket union I wish to express our deepest condolences to the Maynard family.
"I can assure them that our thoughts and prayers are with them."
According to an AFP report, the British transport police treated the incident as "non-suspicious".
Police said they had tried to pull over a man fitting Maynard's description who was driving a car "erratically" in the area an hour before the player was found on the train tracks.
"The male driver of the vehicle - a black Mercedes C250 - made off on foot," the Metropolitan Police was quoted saying.
"Officers were unable to locate the man."
Maynard played for Surrey in a Twenty20 match against Kent on Sunday.
He never played for England but was a member of the country's second-string Lions team.
