SAN DIEGO — Junior Seau’s induction into the Pro Football Hall of Fame was always going to be awkward, a chance to celebrate a marquee player known for his bone-crushing career while not dwelling on the injuries that might have precipitated his death.

When his induction was announced at the Super Bowl, his family rejoiced and started thinking about what to say at the ceremony in Canton, Ohio, on Aug. 8. Seau had told them that if he ever made it, he wanted his daughter, Sydney, to introduce him.

But the Hall of Fame does not plan to let Sydney or anyone else speak on Seau’s behalf. Instead, it will show a video commemorating his career, while avoiding questions about his suicide in 2012 at age 43 and the subsequent diagnosis of traumatic brain injury that doctors said they believed was brought on by hits to his head.

Nor will the video mention the lawsuit that Seau’s family has filed against the N.F.L., which is trying to curb injuries in active players and address brain disease among its almost 20,000 retired players.
