The Buffalo Bills are hosting Clemson wide receiver Sammy Watkins on a pre-draft visit Wednesday.

Watkins is widely considered the top wide receiver available in next month's draft and could be off the board by the time the Bills select at ninth overall. In order to pick Watkins, the Bills would likely have to trade up.

The Bills don't have an immediate need at wide receiver after trading for veteran Mike Williams earlier this month, but Watkins is a talent that would be hard to pass up. The Bills have also hosted Texas A&M's Mike Evans and LSU's Odell Beckham Jr., considered the next best receivers in the draft, on visits.

The Bills also hosted Notre Dame offensive tackle Zack Martin and McGill offensive lineman Laurent Duvernay-Tardif on visits Wednesday. Martin is a potential first-round pick and could challenge Michigan's Taylor Lewan and Texas A&M's Jake Matthews as the second offensive tackle off the board, following Auburn's Greg Robinson, who is considered the best tackle available.

Duvernay-Tardif is considered a mid-to-late round pick but would still fill a position of need for the Bills.
