Source: Eric Berry plans to return to Chiefs on Sunday

Kansas City Chiefs star safety Eric Berry, who has not yet signed his one-year franchise tag and has missed the entire preseason, plans to return to the team Sunday, according to to ESPN's Adam Schefter and multiple reports.

Chiefs coach Andy Reid had hoped as recently as Tuesday that Berry would return in time for the regular-season opener against the San Diego Chargers, saying that the four-time Pro Bowler could even play on Sept. 11 without appearing in Kansas City's final preseason game.

As an unsigned, franchise-tagged player, Berry was not required to report to training camp, and the club cannot fine him for not reporting.

Berry's one-year franchise tag salary is $10.806 million for the 2016 season. The deadline for extending contracts for players on franchise tags passed July 15.
