The NFL and NFLPA went through an 18-week lockout during the 2011 offseason, but the two parties were able to come to an agreement on a new 10-year CBA, less than two months before the regular season took place.

But now, Los Angeles Rams running back is warning fans to be prepared for another lockout in 2021, when the current CBA expires. Speaking to Cameron DaSilva of Rams Wire, Gurley explained that the players will want to get more guaranteed money in their contracts.

"For right now, we just need to come together and be prepared, Gurley said. "You always have to be prepared. We'll just come together, pull up a couple different ideas and go on from there. You definitely always have to be prepared for certain situations."

Gurley also recently explained to TMZ Sports earlier this month"that NFL players are in the most need of fully guaranteed contracts," given its "level of brute, immanent physicality, high turnover as well as the short life cycle of its participants."

As is the case with every new CBA agreement, the players and owners will have plenty to discuss and negotiate through, besides guaranteed money. One hot topic heading into the 2018 season is the new rules on player anthem protests.

The NFL introduced a new ruling in that players had the choice to stay in the locker room during the anthem. However, those who stayed on the field would not be allowed to protest, otherwise they'd be subject to a fine. However, the NFL and NFLPA announced on Thursday that they'll discuss the issue and try to find a resolution.

There will surely be other matters that the players, owners and league officials will have to discuss when the CBA runs up in three years. But for now, the focus will be on finding a solution with the anthem protests before the 2018 season begins. And finally, fans should be prepared for a 2021 lockout, as Gurley warned.
