Australian cricketer Phil Hughes passed away after being hit on the head by a bouncer. We bring you 15 more such depressing incidents where sports persons have died while playing:

1. Ayrton Senna

Brazilian F1 driver Senna's is perhaps the most famous on-field death in sporting history. The 3-time world champion was a legend in the sport even before his untimely death at the 1994 San Marino Grand Prix. Leading in lap 6, Senna collided with a wall at 135 mph while taking a turn. Despite being air lifted and rushed to hospital, Senna had suffered significant blood loss and trauma and was later declared dead. God only knows how many more championships Senna would've won if this mishap had not taken place!

3. Cristiano Junior

The Brazilian striker was playing for Goan club Dempo in the Federations Cup final versus Mohun Bagan in 2004. Having already scored one goal, Junior jumped to head in a second goal but, in the process, was punched in the chest by Bagan keeper Subrata Paul. The 25-year-old immediately collapsed on the pitch and was later declared to have died of a stroke. But the ball had sailed into the net and the goal stood. Dempo went on to win the match 2-0 with Junior getting a brace. The Brazilian passed away doing what he loved doing most: scoring goals!

4. D. Venkatesh

Yet another footballer to die in India. During an A-division league match in 2012, Bangalore Mars player D. Venkatesh had come on as a substitute before collapsing in the dying minutes of the match. He was being rushed to hospital in an auto rickshaw as there was no ambulance available when he died en route. It's believed that had there been medical personnel and oxygen available at the stadium, Venkatesh's life could've been saved.

14. Frank Hayes

The jockey had never won a race in his life and was in fact not even a jockey but a horse trainer. Nevertheless, the 35-year-old was competing in a steeplechase event in 1923 when he suffered a mid-race heart attack. But his body remained in the saddle and his horse was the first one to cross the line. His death was not discovered until others rushed to congratulate him and found his lifeless body slumped on the horse. Hayes literally went a winner!

15. Duk Koo Kim

Many boxers have lost their lives in the ring but one of the most famous incidents involved the 23-year-old South Korean Kim. He was contesting in the championship bout with Ray Mancini which turned out to be a bloody affair. Mancini had suffered a torn ear and a swollen eye but Kim came off worse with severe swelling in the head. In the 14th round, following a sequence where he was hit 39 times in a row, Kim collapsed and went into coma. He died 4 days later and this led the WBC to reduce the number of bouts from 15 to 12.
