Eddie Yarbrough started at defense end last week in place of Shaq Lawson, who was a first-round pick in 2016.
Asked Monday what caused that change, Buffalo Bills coach Sean McDermott said, "Really, it was just a situation for us that I’m going to keep between Shaq and myself at this point."
Lawson seems to have atoned for whatever issue he was disciplined for. He declined to go into specifics Wednesday but said he will return to the starting lineup this week.
"Oh yeah. Just a one-week thing," Lawson said. "Between me and him, everything's clear."
Lawson played 39 snaps of 58 defensive snaps against the Chiefs, about two-thirds, which is on par with his usual average. Jerry Hughes, who started on the other side, played 40 snaps while Yarbrough played 19 and Ryan Davis played 18. Lawson has only three sacks, but that's tied for the team lead with Hughes and Lorenzo Alexander.
