Buffalo Bills sign Sammy Watkins

ORCHARD PARK, N.Y. -- Buffalo Bills wide receiver Sammy Watkins, the team's first-round draft pick, signed his rookie contract Wednesday.

Watkins was selected fourth overall. The Bills included their 2015 first-round pick in a trade with the Cleveland Browns to move up from the No. 9 pick to draft Watkins.

Watkins set career records at Clemson with 240 receptions and 3,391 receiving yards. He also tied former teammate DeAndre Hopkins with 27 career touchdowns for the most in school history.

Bills general manager Doug Whaley said Watkins was the top-rated player on their 2014 draft board. The Bills traded fellow receiver Stevie Johnson one day after selecting Watkins, clearing the way for Watkins to be the Bills' top receiver this season.

Watkins participated in the Bills' organized team activity Wednesday, his first chance to work with second-year quarterback EJ Manuel.

However, Watkins will not be participating with his new teammates on Thursday and Friday as he will be attending the NFL Players Association's rookie premiere in Los Angeles.

"It's not his fault that he's not going to be here the next two days, I wish he was," coach Doug Marrone said Wednesday. "Looking back I made a note that I should have had practice [Tuesday] so I only would have lost him one day. My mistake on that."

The Bills now have six of their seven draft selections under contract. Second-round pick Cyrus Kouandjio has yet to sign his deal.
