San Francisco 49ers Richard Sherman expects a lockout is coming

San Francisco 49ers cornerback Richard Sherman said Thursday he believes a lockout is coming.

"It's going to happen, so it's not like guys are guessing," said Sherman, who is the team's player representative. "We don't plan on changing anything about the deal we currently have now ... I don't think it's going to be negotiated before the end of the CBA [Collective Bargaining Agreement]."

The current CBA expires after the 2020 season.

The last lockout occurred during the 2011 offseason, which lasted four months before the owners and players agreed to a 10-year deal before the regular season kicked off.
