San Francisco 49ers offensive lineman Trent Williams and his wife, Sondra, shared the heartbreaking news of their newborn son's passing on Sunday. Sondra Williams posted a moving tribute to their son, Trenton O’Brien Williams Jr., on social media.

In her post, Sondra described the difficult experience of welcoming and saying goodbye to her son in the same moment. Trenton was born prematurely at 35 weeks, weighing 4 pounds 8 ounces and measuring 18.5 inches long. Sondra expressed gratitude for the support of her sister and the attending nurse during the delivery. She also revealed the prior loss of Trenton's twin earlier in the pregnancy and shared that Trenton had been diagnosed with Trisomy 13. Despite the pain, Sondra found solace in her belief that Trenton is now a guardian angel watching over their family. She shared the bittersweet joy of having carried him for 35 weeks and the profound sadness of leaving the hospital without him, particularly during the Thanksgiving holiday. Sondra concluded her message with a declaration of love for Trenton, their "Forever Angel."

Williams was absent from the 49ers' game against the Buffalo Bills on Sunday night.
