Davis, projected to be a first-round pick, continues to recover from surgery he had on his ankle in January, which also kept him from performing drills at the NFL combine.
League sources told ESPN's Adam Schefter last month that Davis' ankle injury was "extremely minor." Davis' recovery timetable puts him on track to be ready in time for minicamps, a source told Graziano.
A 6-foot-2, 205-pound receiver, Davis had 332 catches, an FBS-record 5,285 yards and 52 touchdowns (19 this season) at Western Michigan.
ESPN's Mel Kiper's has Davis ranked second among wide receivers eligible for the 2017 NFL draft.
