The Ravens claimed Watkins off waivers from the Green Bay Packers on Tuesday, the same day receiver Devin Duvernay injured his right foot in practice.
Reporters at the Ravens' facility noted that Duvernay limped off the field early at practice Tuesday. NFL Network later reported that Baltimore has concern Duvernay's injury is "significant" with tests scheduled to determine the severity.
Duvernay, a 2020 third-round pick by Baltimore, had 37 receptions for 407 yards and three touchdowns in 14 games this season. Rashod Bateman, who suffered a Lisfranc injury in late October, was already lost to season-ending surgery.
