Chicago had placed a "transition" tag on him, meaning that if another team would be willing to pay the required transition salary ($12,906,700/year) for Fuller and the Bears don't, they could take him.
Rapoport said the Bears increased Fuller's guaranteed money in his contract, $18 million of the four-year, $56 million deal, keeping him.
Fuller has eight career interceptions with the Bears after three seasons. Chicago picked him in the first round of the 2014 draft. Many analysts consider him a top 10 or 15 cornerback in the NFL.
