Former NFL quarterback Ryan Mallett died on Tuesday in an apparent drowning at a Destin, Fla. beach.

His friends and former teammates, including Tom Brady, have shared heartfelt messages on social media in recent days, and posts continue to pour in.

Mallett's ex-wife, Tiffany Seeley, shared posts on both her Instagram story and Facebook, saying her "heart breaks for everyone."

"Just want to say thank you to everyone who has reached out," she wrote on Instagram with a broken heart emoji. "My heart breaks for everyone." In the message, she shared a photo she had previously posted to her account of the two together.

"Just want to say thank you to everyone for reaching out these last few days. Sorry if I haven’t responded but the messages don’t go unnoticed. My heart breaks for everyone who knew him," she wrote in her Facebook post, via People.

Mallett and Seeley married, and separated, in 2020, which Seeley says was caused by "cheating."

"We began building a new beautiful home across from my grandparents in cotter and we got married. Then came Covid, cheating, and drama around the corner to wake me up from this fairytale I thought I was living," Seeley wrote in a 2020 Facebook post

While an investigation is still underway, officials did say that there were "no rip currents" present when Mallett drowned.

"Flag condition was yellow. A yellow flag indicates medium hazard, moderate surf and/or currents," Destin Beach Safety said. "There were no rip currents present in the area in which we responded to Ryan Mallett."
