Seattle Seahawks running back Marshawn Lynch will be out of the field because he just underwent a surgery for his sports hernia injury.

Citing a source familiar with the current medical situation of Lynch, Ian Rapoport informed that the 29-year-old football player's operation was done on Wednesday, Nov. 25, NFL.com reported.

Seahawks coach Pete Carroll confirmed the news on Lynch, ESPN informed. Carroll also relayed that his player may only be only out for a month.

"The doctor was very optimistic about a quick recovery. And that could mean within three or four weeks," Carroll said.

The Hawks' mentor does not dismiss the probability that the Oakland, California native may not be back this season to support his team. However, he is also thinking that he can recover fast enough to return soon.

How is Lynch doing now?

Hawks' cornerback Richard Sherman gave an update about his friend and teammate.

"He's in good spirits...He obviously knows, playing this game for nine years or so without having surgery, so he's kind of surprised by the way it went down. But he's doing fantastic," the Stanford University alumnus said.

What if he can't return this 2015 season?

Seahawks' member Fred Jackson, who also plays the role as Lynch does, shared that his longtime friend could have an important career move if that happens.

"When you get nine, 10 years in the league, you start to try to figure out the plan after football anyway. But talking to him, I can't tell you what he's going to do after the surgery or not. I think that's a decision he's going to have to make when it comes time to make that," Jackson said.

In June, Lynch acknowledged on Conan O'Brien's show that one does not "go that long" in a running back position, NFL.com reported. He only reconsidered playing again this year when he was offered a deal that made him think, "Yeah, maybe I can do this again."

In March, Seahawks and Lynch agreed to a two-year extension contract that will give him "$12 million in 2015, $9 million in 2016 and $10 million in 2017," NFL.com noted, citing a source knowledgeable about the matter.

However, in February, retired Seahawks fullback Michael Robinson shared that his friend was thinking of retiring as he wanted to enjoy more important aspects of his life. Robinson noted that Lynch realized how playing the running back position for a long time had already taken its toll on his body, ESPN informed.
