We are not involved in this matter."McCarthy admitted the NFL has given money to Boston University to study brain injuries, but said they are not involved in any other way with the research.A Seau family friend confirmed the family has made a decision about the star linebacker's brain, but is keeping that decision private.At a private viewing for invited guests at Calvary Chapel in Oceanside on Friday, more than 1,000 mourners, many wearing traditional Polynesian clothing, gathered to say their goodbyes.When the hearse carrying Seau's body pulled in front of the chapel, a quiet ceremony took place, involving fine woven mats that were folded and placed on the gurney where Seau's casket was placed. Seau's family appeared to be praying before his body was taken inside.Guests told 10News it was a somber scene inside. Alongside Seau's open casket sat both his parents, with grandchildren fanning them and paramedics standing by in case anyone needed medical attention.Seau will be buried Friday at Eternal Hills Memorial Park, not far from the Oceanside home where authorities said he fatally shot himself.
