Fuller can negotiate with other teams under the transition tag, but the Bears have the right of first refusal to match any offer sheet Fuller gets.
The Bears just completed a 2017-18 campaign in which Chicago won just five games, marking their fourth straight losing season.
Per NFL Network's Ian Rapoport, the Bears reportedly will place the transition tag on Fuller.
Last offseason, the Bears opted to decline the fifth-year option on Fuller, which would've applied to the 2018 season.
The Bears will have the chance to match any potential contract offers Fuller receives from another team when free agency begins on March 14. Now the Bears should be able to hold onto him, and they'll save a little money compared to what they would have paid with the franchise tag. This year, Fuller had 22 passes defended for the Bears and grew into the sort of lockdown role on the outside that the Bears pictured when they invested such a high pick. Pace can also try to work out a long-term deal with Fuller, which would need to get done by the July 16 deadline. He collected three interceptions and two forced fumbles in his first three games of his rookie season.
That's bad news for Chiefs fans who wanted to see their favorite team bring in Kyle Fuller to play alongside his younger brother, Kendall Fuller, who was a primary part of the prize when they traded Alex Smith to Washington in January.
