London: Ryan Mason's retirement after he failed to recover from a serious head injury sufficiently enough to return to the pitch had "devastated" Gary Cahill, the Chelsea defender has said.
Mason announced his retirement from soccer on Tuesday after he suffered a fractured skull following a head clash with Cahill while contesting a corner during Hull City's defeat to Chelsea in January 2017.
"Devastated to hear today's news from Ryan," Cahill said on his official Twitter account.
"Competing for a corner is something we've done thousands of times and to see those consequences for a top professional like Ryan is heartbreaking.
"Sending all my love to him and his family, and wishing him the best for the future."
