Lawson was ejected during the third quarter of last Sunday's 24-21 victory for fighting with Jaguars running back Leonard Fournette, who was suspended without pay for one game. Fournette sat out Sunday's contest versus the Indianapolis Colts.
Players began shoving each other after Jacksonville wide receiver Donte Moncrief reeled in what was initially ruled a 30-yard touchdown reception. The 6-foot-3, 267-pound Lawson went after Jaguars running back Carlos Hyde, prompting Fournette to run across the field and intervene.
Hyde was fined $13,369 for unsportsmanlike conduct.
Lawson has collected 20 tackles, two sacks and a forced fumble in nine games this season for the Bills.
The 24-year-old Lawson has recorded 66 tackles, eight sacks and three forced fumbles in 30 career contests since being selected by Buffalo with the 19th overall pick of the 2016 NFL Draft.
At Clemson, Lawson led the country with 25.5 tackles for losses and was a consensus first-team All-American in 2015. However, he was limited to 13 tackles and two sacks while appearing in 10 games, mostly in a reserve role, as a rookie.
