Report: NFL warns Bucs' Arians over sideline conduct in Saints game

The NFL sent former Tampa Bay Buccaneers head coach Bruce Arians a warning about his conduct on the sideline during Sunday's game against the New Orleans Saints, a source told ESPN's Jenna Laine.

The league warned Arians that similar conduct in the future will result in discipline against him and the team, Laine adds.

Arians, who stepped down as the Bucs' head coach this year after three seasons, serves as senior adviser to general manager Jason Licht. Both were on the sideline during Tampa Bay's 20-10 victory in Week 2.

The 69-year-old Arians appeared irritated when referees didn't call pass interference on Saints cornerback Marshon Lattimore following a Tampa Bay incompletion on third down. Arians exchanged words with Lattimore minutes before a fight broke out among players from both teams, which resulted in Lattimore's and Bucs wide receiver Mike Evans' ejections from the contest.

Buccaneers head coach Todd Bowles said Arians and Licht were on the sideline because the Saints didn't provide a booth upstairs, according to Laine. New Orleans denied Bowles' comments, saying it offered accommodation in the press box.

Evans received a one-game suspension for his role in the brawl. The four-time Pro Bowler has appealed the ban.
