Les Ferdinand is among the current and former players who are devastated at the news that Hull City midfielder Ryan Mason will have to hang up his boots.
The Chelsea and England defender tweeted: "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".
However, Hull released a statement on Tuesday to announce that Mason had retired from the sport with immediate effect. He was able to return to action within three months and sympathised with Mason.
"I am so proud to have come through the ranks to play for my club, the club I love", he said. To have had the honour of captaining the team fills me with vast pride.
Mason made his England debut in2015, an honour "nobody can ever take away from me".

While Cahill was deemed fit to continue in the match, Mason was stretchered off while receiving oxygen.
'Of course the door is open to help him; myself, the coaching staff and the club, because we love him and all his family.
Cech, who has personal experience of skull injuries after a sickening clash with Reading midfielder Stephen Hunt in 2006, has called Mason an inspiration.
Cech said on Twitter: "Yesterday was a sad day for one incredible young man.@RyanMason".
"Don't worry Ryan, you're going to be a successful person outside of the club".
Now, Pochettino has offered his thoughts on Mason's retirement, calling him a special player as he was one of the first players to represent Tottenham's change in approach under Pochettino's management.
