The Broncos placed Watson on the active/non-football injury list Wednesday with an undisclosed injury, Aaron Wilson of KPRC 2 Houston reports.
Watson appears to have sustained his injury away from Denver's practice facilities. The undrafted rookie out of Memphis will be eligible to return to practice at any point throughout training camp or the preseason, once cleared, but any amount of time missed will negatively impact his chances of earning a depth role in the Broncos backfield.
