Sources: Von Miller to visit top 10 teams

Texas A&M outside linebacker Von Miller has two upcoming visits with teams holding very high picks in the NFL draft, according to sources.

The sources said Miller will meet with the Buffalo Bills on Wednesday and Thursday, as well as hold a two-day visit with the Cleveland Browns on April 11-12. Miller is widely considered this year's top linebacker prospect.

Miller is also part of the NFLPA's lawsuit against the league that includes high-profile players Tom Brady and Peyton Manning. There is some speculation about whether Miller could be blackballed by owners and teams, which would hurt his draft stock. But that doesn't appear to be the case, as Buffalo (No. 3 overall) and Cleveland (No. 6) both hold top picks in the first round.

Miller wowed scouts at the NFL combine with his athleticism and recently ran a blazing 4.49 40-yard dash during his pro day at Texas A&M. The senior recorded 68 tackles, 11 sacks and an interception for the Aggies last season.

The Bills and Browns were ranked No. 24 and No. 22 in total defense, respectively, and both could use help in their front seven.

Despite labor uncertainty, the NFL draft will begin on April 28 in New York City.
