Oxfordshire's Jack Brooks has, as expected, decided to leave Northamptonshire.
The former Tiddington and Oxford seamer, 28, progressed to Northants via Minor Counties cricket with Oxfordshire and Surrey 2nd XI.
And it has now put him on the fringes of England’s plans, taking 118 first-class wickets at under 29 each since making his first-class debut in 2009.
“I’ve taken this decision to leave Northants, because I want to compete at the highest level possible,” said the England Lions bowler.
“The opportunities being offered to me are too good to turn down, and I owe it to myself to explore all avenues as I continue my quest for international honours.
“I have thoroughly enjoyed my time at Northants and fully appreciate the support I’ve been given by all at the club.
“I hope I’ll be remembered for my performances and whole-hearted approach to the game.”
Northamptonshire’s head coach David Ripley said: “I am saddened by Jack’s departure.
“We will miss him both on the field and in the dressing room, because he is a real character.
“We wish him all the best.”
