Los Angeles Chargers safety Derwin James Jr. entered concussion protocol after administering a hit that led to his ejection from Monday night's 20-3 win over the Indianapolis Colts.
James was flagged for unnecessary roughness at 5:19 of the second quarter after he led with the crown of his helmet while delivering a hit on Colts wide receiver Ashton Dulin.
Both James and Dulin ventured to their respective blue medical tents on the sideline. Dulin was diagnosed with a concussion and didn't return to the game.
Chargers coach Brandon Staley said that he did not agree with the ejection of James.
