Vitt has said the part of the document showing his pledge is false, which he said raises questions about all of the evidence.
However the bounty saga winds up, Fujita said he has no regrets about his aggressive tactics as a union leader.
"I've had a few concussions myself. I have a dear friend (former Saints player Steve Gleason) who has ALS. I have a friend and former mentor (Lew Bush) who died earlier this year. Then there was the tragic death of someone I've admired for so long, Junior Seau," Fujita said. "I can't say for sure that all of these things happened because of football, but I've seen enough to have some concerns. I was elected to fight for these men, so in no way do I regret that."
