Today, after over eight years in the National Football League, Calvin ‘Megatron’ Johnson announced that he will be quitting pro football.

Rumours have been flying around since the final game of the regular season, in which the Detroit Lions defeated the Chicago Bears at Soldier Field, that Calvin would be calling it a day and after much speculation, he has decided to do just that.

He has been Detroit’s franchise player for a number of years since being drafted second overall in the 2007 NFL Draft.

He holds the NFL record for receiving yards in a season but was unable to get Detroit a playoff win, with the Lions last win in the postseason coming in 1991 against the Dallas Cowboys.

It is a sad day for many Lions fans, who see another of their all-time greats leave the game early, after Barry Sanders left the Lions in 1999 after falling out of love with the game whilst on the verge of breaking the NFL all-time rushing record.

We’ve created a timeline of Megatron’s career in pictures in honour of one of the greatest players of all time.
