With the latest batch of news on Thursday, it seems all 30 of the Buffalo Bills' pre-draft visits have been revealed. Four more players came through One Bills Drive to meet with the staff and see team facilities.

The group consisted of Tennessee quarterback Tyler Bray, Tennessee wide receiver Justin Hunter, Rice tight end Vance McDonald and Fresno State safety Phillip Thomas.

This is the second time the Bills have met with Bray recently, having put him through a private workout earlier in April. The quarterback is considered to be a Day Two pick in the 2013 NFL Draft.

His college teammate Patterson was not a part of the private workout with the Bills, while his teammates Justin Hunter, Zach Rogers and Mychal Rivera ran routes and caught passes for Bray. Patterson is thought to be a potential first round pick.

McDonald and Thomas each are players thought to be in the mix to go anywhere from the second to fourth rounds. McDonald was one of the winners at the NFL Combine by displaying his impressive speed and athleticism that went along with his size (6-foot-4, 269 pounds).

The Bills have now conducted 27 official pre-draft visits, and the other three have leaked out through various reports. Teams in the NFL are alotted 30 leading up to the annual selection meeting in New York City.
