New England Patriots quarterback Tom Brady says the team is moving forward from the "tragic" event that led to the arrest of Aaron Hernandez on a murder charge.

Brady says it's sad when a teammate is involved. And he says the Patriots are trying to move on from a "challenging offseason" with better awareness of "these types of things."

He spoke on the opening day of training camp on Thursday.

Hernandez was one of Brady's top receivers as a tight end the past three seasons. The Patriots cut Hernandez on June 26 after he was arrested that morning and before he was charged that day.

He is being held without bail after pleading not guilty in the shooting death of Boston semi-professional football player Odin Lloyd on June 17.
