England and Durham bowler Graham Onions has been ruled out for the rest of the season after suffering a muscle tear against Notts Outlaws, while veteran spinner Gareth Breese will leave at the end of the campaign.
Scans revealed that the injury picked up in Tuesday's win over the Outlaws in the Royal London One-Day Cup will take around six weeks to heal, effectively ending the Gateshead-born bowler's participation this summer.
Onions, who has taken 27 wickets in an injury ravaged season, had been in good form in the limited overs tournament, taking 11 wickets so far.
He said: "I was obviously devastated when I received the results of the scan as the next six weeks of the season are hugely important for the team"
"Although I don't think I can play for the rest of the season, I'll be doing everything I can to try to get fit and help the lads out during those final few games"
Meanwhile Breese will bring down the curtain on an 11-year spell in the north east next month.
The 38-year-old was part of the Durham side that lifted the club’s maiden County Championship in 2008 and has proved a key performer in limited-overs cricket, with 150 List A wickets in as many appearances including the 2007 Friends Provident Trophy triumph at Lord’s.
"It's been a very enjoyable time for me,” said Breese, who was awarded a benefit year alongside Gordon Muchall in 2014.
"Over the past eleven years, I've grown as a player, coach and a person and most importantly formed some great friendships on and off the field.
"The highlights have been the successes we've had, not necessarily personal, but just winning trophies as part of a team.
"The one that means the most to me was the 2007 Friends Provident Trophy at Lord's, that's the one that really stands out.”
Coaching may lie in Breese’s future as he has been working with Durham’s spin academy but, for now, the popular Jamaican is not getting too far ahead of himself.
He added: “For the immediate future, I'm going to do all I can to try and get us as far as we can in the Royal London Cup and hopefully I've got a few more performances in me to try and take us all the way. That's as far as I'm looking right now.”
