Northampton Town goalkeeper Richard O'Donnell has left the club to sign for Bradford City on a free transfer.
O'Donnell joined the Cobblers in January, and has activated a clause in his contract that allowed him to move on.
"Richard goes with our best wishes for the future," said manager Dean Austin.
"When the club was signing players in January, due to the nature of our league position and in order to secure the signings of one or two of the January 2018 arrivals, the club agreed to clauses in their contracts when they signed that allowed them to move on in the event of relegation if an opportunity came up for them.
"Richard came to us soon after the end of last season to activate that clause and he said he wanted to leave. He lives in Yorkshire and so geographically this move works well for him and his young family. I would also like to add that Richard and his agent have handled things very professionally and we part on good terms.
"Now we have to move forward and this gives us an opportunity. We are looking to add another goalkeeper to the squad in due course and that work has been going on in the background in preparation for this."
