The contracts of overseas signings Faheem Ashraf and Kieron Pollard have been cancelled.
Faheem was due to spend the first half of the season at The County Ground, with Pollard set to feature for the Steelbacks in the Vitality Blast.
The contracts of both players were cancelled after a mutual agreement between the Club, players and their management.
“It’s obviously really disappointing as they’re superb players and there was a real buzz around them joining the squad.” Head Coach David Ripley said.
“I’d really like to thank the players and their management for their understanding and cooperation.”
Chief Executive Ray Payne is hopeful fans will still have the opportunity to see Faheem and Pollard in Northamptonshire shirts in the future.
“There are a lot of ifs, buts and maybes,” said Payne.
“We don’t have any schedule yet for next season so those players don’t know where they’re going to be. But once we’ve got a schedule, we’ll definitely be talking to them about coming back.”
