Free agent wide receiver Leonte Carroo has been suspended for the first four weeks of the 2019 season, a source tells Field Yates of ESPN.com (on Twitter). Carroo, a 2016 third-round pick, was non-tendered by Miami this offseason. 
Carroo had some hype behind him coming out of Rutgers, but never produced at the pro level. After three seasons in South Beach, Carroo has just 12 catches for 192 yards and two touchdowns to his credit. More than one-third of those yards came on a 74-yard TD against the Colts last season in which he wrestled a defender to the ground and waltzed into the end zone.
The exact reason for Carroo’s ban is not yet known, but it is likely for a violation of the substance abuse policy or the league’s policy on performance-enhancing drugs.
