Ryan Mason says he was “100% sure” he would return to football until just a few weeks ago.

The Hull City midfielder, 26, announced his retirement from football on Tuesday, after suffering a fractured skull against Chelsea in 2017.

A recent CT scan showed the injury’s effects were more serious than had previously been realised.

“That was a few weeks ago now and everything has really changed since then,” Mason told the club website.
