CALGARY - Kevin Martin and John Morris are going their separate ways after seven years.
The two curlers released a statement on Wednesday night, saying Morris was leaving Martin's rink, which includes second Marc Kennedy and lead Ben Hebert.
"Unfortunately we have had a challenging past few seasons and have not lived up to our expectations of being the best curling team in the world," said Morris.
After forming prior to the 2006-07 season, the foursome was one of the most dominant in the curling's history, capturing the Tim Hortons Brier in 2008 at Winnipeg and 2009 at Calgary, both with undefeated records.
The Martin rink also won the world men's championship in 2008 at Grand Forks, N.D., and finished second a year later at the World Men's Championship in Moncton, N.B.
The team also won a gold medal for Canada at the 2010 Winter Olympics in Vancouver.
