The Chad Tough movement united B1G rivals two months ago. On Sunday, they united two more rivals.

While Peyton Manning and Tom Brady battled for the right to go to the Super Bowl, they were together in their support of the Chad Tough movement.

Tammi and Jason Carr’s 5-year-old son, Chad, died of a brain tumor last November. Both AFC Championship quarterbacks reached out to the Carr’s and offered their condolences.

Brady, who was teammates with Jason at Michigan in the late 1990s, met with the family following a game in Miami in December. On Sunday, Tammi shared the picture they took with him when they were on vacation.

As it turned out, Manning also reached out to the Carr family after he saw the ESPN feature on Chad following his death. Manning sent them a hand-written letter and quoted scripture in offering his condolences to the family.

The letter had such an impact that Tammi said in her Instagram post that she was rooting for both quarterbacks during Sunday’s showdown.

The organization is continuing to raise money to end the fight against pediatric brain cancer. To donate or reach out to the Carr family, go to ChadTough.org.
