ORCHARD PARK, N.Y. — The Buffalo Bills have their entire 2019 draft class under contract after signing rookie tight end Dawson Knox to a four-year deal.

The Bills announced the signing Friday, a day after completing their series of off-season mandatory practices and six weeks before the team reports to training camp in suburban Rochester, New York. Buffalo gave up two fourth-round picks to move up in the draft order to select Knox in the third round.

Knox had 39 catches for 605 yards in 28 games at Mississippi. Buffalo signed its other seven rookie draft picks in early May.

Buffalo also shuffled tight ends by claiming Keith Towbridge waivers and releasing Mik'Quan Deane. Towbridge was claimed a day after being released by the Tennessee Titans, and returns to Buffalo, where he has spent parts of the previous two seasons.

The Bills also announced their training camp at St. John Fisher College will run from July 25 through Aug. 6.
