Winger Lee Martin has now moved to Northampton Town on a month long loan spell.
It was expected that the 28 year old would move on this month in the search for more regular first team football as his opportunities so far this year have been limited, and he has only made eleven appearances for manager Neil Harris so far.
He has however been a regular in the Under 21 set up under Justin Skinner and has been pivotal in their run of seven wins and one draw from the last eight games.
Last season he made 29 appearances, scoring three times and he heads to Sixfields on a deal that will expire in 28 days.
The move has gone through in time for him to potentially make his debut in their trip to Dagenham and Redbridge on Saturday.
