Clarke heads to Cobblers

The 33-year-old signed a two-year deal at Sixfields following his release from the U's earlier on Thursday to link up with boss Chris Wilder once again.

On his exit from the Kassam Stadium, Oxford boss Michael Appleton told the club's official website: "Ryan has done great for the club but we feel the time is right for everyone to make a change.

"We would like to thank him for his efforts and wish him well for the future."
