Texas A&M offensive tackle Jake Matthews and Louisville linebacker Preston Brown are visiting the Buffalo Bills today.
Matthews is a potential high first-round draft pick.
He's the son of Hall of Fame offensive tackle Bruce Matthews.
Matthews was a first-team All-American who started 45 consecutive games.
Brown was a three-year starter at Louisville who led his team in tackles last season.
The 6-foot-1, 251-pounder had 13 tackles in the Sugar Bowl against the Florida Gators.
He finished with 301 career tackles.
Brown ran a 4.86 40-yard dash at the NFL scouting combine and a 4.79 at the Louisville Pro Day.
