Oxford United manager Chris Wilder has made his fourth capture of the summer by signing Wycombe Wanderers striker Jon-Paul Pittman.

The 24-year-old, who made 77 appearances for the Chairboys, has agreed to sign a two-year deal after being released by Wycombe.

The American-born striker scored the equaliser for Wycombe after coming on as substitute in the 2-2 draw at the Kassam Stadium last month.
