The Detroit Lions have revealed that star man Calvin Johnson had surgery on finger and knee injuries last week.

Wideout Johnson ranked in third spot this season in terms of receiving yards with 1,492 in total, despite catching fewer passes than anybody else inside the top eight.

Lions general manager Martin Mayhew announced that 'Megatron' had undergone his double operation when he addressed the media on Wednesday.

Mayhew told reporters: "Calvin played the entire season with a finger really that was pointing perpendicular from his body the whole season. He's trying to catch the ball like that. He would never complain about that, but certainly that was a factor, I think, in the way he played.

"The op was really just a minor issue though. He's going to be fine."

It was announced last week that the pair of problems for Johnson were expected to keep him out of the season ending Pro Bowl, which will be played in Hawaii next weekend.
