When we arrived in the office this morning, we saw #ThankYouDanielBryan on Twitter and our hearts sank.

The former WWE champion has announced his retirement because of medical reasons, with immediate effect.

The Yes Man is retiring after claiming:

“It gets to the point where you’ve been wrestling for 16 years, that adds up to a lot of concussions,”

“It gets to a point where they tell you you can’t wrestle any more.”

Bryan, retires after a wonderful 16 year career, here’s 10 of his greatest ever WWE matches.

We will miss you Daniel!
