Former 49ers Player Files Explosive Lawsuit After Learning First Child Isn’t His

A shocking off-field story has emerged involving former San Francisco 49ers defensive lineman Ian Williams, as court documents reveal he has filed a lawsuit against his wife over alleged paternity deception concerning their first child.

According to the filing, the truth surfaced only recently when the couple’s eldest son required a blood transfusion for surgery. Routine testing revealed neither parent’s blood type matched the child’s, triggering immediate suspicion and further investigation.

Subsequent DNA testing confirmed Williams is not the biological father — a revelation that, according to the suit, has left the former NFL veteran devastated. The petition outlines claims of emotional distress, fraud, and marital betrayal.

"She said that all I ever did was come home from practice exhausted and fall asleep... But while I was out there fighting in the red and gold of the 49ers, giving everything to build our life together, she was building a life with someone else." Ian Williams said in a statement to reporters.

Williams, now 36, went undrafted out of Notre Dame in 2011 and spent his entire five-year NFL career with the San Francisco 49ers (2011-2015). He appeared in 45 games with 20 starts, recording 54 tackles and 1.5 sacks as a reliable nose tackle in the defensive line. Known for his strength against the run, work ethic, and leadership despite battling injuries (including a career-ending neck issue), he was a quiet contributor during the Jim Harbaugh era.

Friends and former teammates expressed shock at the situation, with some noting Williams had often spoken about family and community involvement, including his ties to the Boys & Girls Club in his hometown.

Legal experts say the case could set precedent in California for damages tied to paternity deception.

As the legal battle begins, Williams says his focus is on protecting the well-being of the child while seeking accountability for what he calls the deepest betrayal of his life. The first court hearing is expected later this year.

The San Francisco 49ers have announced they will cover the full cost of cancer treatment for one of the most revered figures in franchise history
SANTA CLARA, Calif. — December 26, 2025 — The San Francisco 49ers are once again demonstrating that their legacy is measured by more than Super Bowl banners. In an emotional announcement Friday, the organization confirmed it will cover the full cost of cancer treatment for franchise icon Roger Craig, one of the foundational stars of the dynasty era. The decision was shared publicly by team CEO Jed York, underscoring a belief that has long defined the 49ers culture — once you are part of this family, that connection does not fade with time. This was not a ceremonial tribute. It was a commitment rooted in gratitude. “Roger helped define what it meant to be a 49er during one of the most important eras in our history. Now it’s our responsibility to stand beside him. Once you are part of the 49ers family, you are never alone.” For Craig, 65, the challenge now moves beyond the field where he once reshaped the running back position. The three-time Super Bowl champion is confronting cancer with the same toughness and quiet confidence that made him indispensable to San Francisco’s championship core. From 1983 to 1990, Craig became one of the most versatile backs in NFL history. He was the first player ever to record 1,000 rushing yards and 1,000 receiving yards in the same season — a groundbreaking achievement that changed offensive strategy league-wide. His résumé includes four Pro Bowl selections and an Offensive Player of the Year award. Yet inside the locker room, teammates often spoke of his discipline and unselfishness. Craig was the steady presence behind Joe Montana and the West Coast offense’s precision. He didn’t seek the spotlight. He embraced responsibility. Craig’s work ethic and team-first mentality helped anchor three championship teams and establish a culture of accountability that defined the 1980s dynasty in San Francisco. Now, as he faces his most personal battle, the 49ers are returning that loyalty. Messages of support from former teammates and the Faithful have poured in, honoring a player whose impact extended far beyond the stat sheet. For the 49ers community, this moment transcends football. It is a reminder that greatness is not only measured in rings — but in standing together when it matters most.
