The Super Bowl halftime performer who unfurled Sudanese and Palestinian flags in an apparent protest action in New Orleans Sunday night will be banned for life from all NFL stadiums and events, an NFL spokesperson told CNN.

A brief protest by a performer at Kendrick Lamar’s Super Bowl halftime show unfurled a flag emblazoned with the words Sudan and Gaza, two wars in the Middle East that have killed tens of thousands of people.

The NFL said the person was part of the 400-member field cast and had hidden the flag on himself before the halftime show began Sunday night.
