On the day many players fear for their jobs, Bears right guard Kyle Long gained some well-earned job security.

According to the NFL Network's Ian Rapoport, the Bears signed Long to a four-year extension worth $40 million with $30 million guaranteed. That's the most guaranteed money for any guard in the NFL, as The Ringer's Robert Mays pointed out.

Long just received quite the pay raise. His rookie contract, which was set to expire after the 2017 season, had an average annual salary of just over $2 million, per Spotrac. So, that's a win for Long.

It's also a win for the Bears. Long, drafted 20th overall in 2013, has been in the league for three seasons. He made the Pro Bowl in all three of those seasons, as a guard in 2013 and 2014 and as a tackle in 2015. Long's better suited to be a guard and he'll transition back to the interior this season. He's also developed a close relationship with oft-maligned quarterback Jay Cutler, once comparing him to Neo from "The Matrix."

Long's battled calf and shoulder injuries this summer, but his coach, John Fox, doesn't appear to be concerned about his status moving forward.

"We're anticipating him at least being back out there to get ready for Houston," Fox said, per 670 The Score in Chicago, a CBS Sports Radio station.

Cutler is also unconcerned.

"Not really that concerned," Cutler said.

As for Long, himself?
