Rugby League: London Broncos are looking for a new head coach just a month into the season following the decision of Joey Grima to step down for personal reasons. Grima, who succeeded Tony Rea last May, wants to take his family back home to Australia. Assistant coach Andrew Henderson, who joined the club from Sheffield Eagles in the close season, will take charge on an interim basis. Grima, a former assistant coach of Parramatta, joined the Broncos as number two to Rea just over two years ago. He was unable to keep them in First Utility Super League last year.

Basketball: German centre Christian Welp, who won the European Championship with Germany and also played in the NBA, has died of heart failure aged 51, the University of Washington said yesterday. Welp, who holds the university’s all-time scoring record, was the number 16 draft pick by the Philadelphia 76rs in 1987 and went on to play two seasons there. He also played for Golden State Warriors and San Antonio Spurs before returning to Europe to play in Greece, Germany and Italy, winning nine championships in as many seasons. Welp became a household name in Germany when he scored the last three points in their 71-70 European Championship win over Russia in the 1993 final.

Athletics: The theft of a Commonwealth Games gold medal won by former heptathlete Kelly Sotherton is to feature in an appeal on BBC1’s Crimewatch programme. Burglars “ransacked” the lower floor of the retired athlete’s home in Sutton Coldfield, West Midlands, last month, taking more than a dozen medals and other personal items. A gold medal won by the British heptathlete and 400m sprinter at the 2006 Melbourne Commonwealth Games was stolen in the raid, along with nine “AAA” British medals and around six gold Island Games medals.

Sailing: Britain’s Olympic sailing hopefuls are taking fish oil and probiotic supplements in the hope it will stop them getting ill from contaminated sea water in Rio de Janeiro. Health hazards posed by raw sewage pumped into the picturesque Guanabara Bay is a big worry for sailors due to compete at the 2016 Games. Cleaning up the bay was a key promise of Rio’s Olympic bid, but the state’s leading environmental official said in January that it would not be able to meet its target of cutting the amount of untreated waste flowing into it by 80 per cent. “The sailors are on various supplements to mitigate against it, but we can’t do anything about the water quality,” the British sailing team’s manager Stephen Park said.
