Several other teams have expressed interest in Royal, but the Bears are the clear front-runner to land the 28-year-old wideout, according to the source.
On the surface, Royal appears to be an ideal fit for a Chicago offense that currently lacks a proven slot receiver, if he can stay healthy.
The eight-year NFL veteran remains a productive player after catching 62 passes for 778 yards and seven touchdowns last season for the San Diego Chargers.
Royal is also a talented and experienced return man, handling punt return and kickoff return duties throughout his career in San Diego (2012-14) and Denver (2008-11).
Just as appealing to the Bears is Royal’s familiarity with Chicago quarterback Jay Cutler.
In the duo’s lone year together with the Broncos, Royal, then a rookie, hauled in 91 receptions for 980 yards and five touchdowns.
In 98 career games, Royal has caught 338 balls for 3,750 yards and 25 touchdowns.
