Cahill revealed he was heartbroken after learning that Ryan Mason had been
forced to retire from football at the age of 26.
Mason sustained a fractured skull in a clash with Cahill during the Premier
League match between Chelsea and Hull City last January, when both players
contested a corner.
The former Tottenham midfielder needed emergency surgery and spent more than
a week in hospital because of his injury.
Mason had hoped to make a comeback this season but announced on Tuesday,
because of further medical advice, that he had been forced to hang up his
boots.
Cahill said on Twitter: "Devastated to hear today's news from Ryan.
"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."
