There are serious fears for the welfare of Jaryd Dawson, brother of Adelaide captain Jordan, after he went missing on Tuesday.

Jaryd hasn’t been seen or heard from since Tuesday afternoon and not made contact with his family.

Jaryd’s wife Jessica issued a desperate plea on social media asking if anyone had seen him.

“If anyone has heard from Jaryd since around 2:30pm yesterday, please let us know,” she wrote on Instagram.

It’s been reported his car and phone have been found.

Jordan missed training on Wednesday as he deals with the situation.

7NEWS understands a large search is underway in the state’s south-east for Jaryd.

According to Jaryd’s social media, he recently became a father to a baby boy last September. He and wife Jessica were married at the end of 2024.

He is the co-founder of boutique home building company Domus Design and Build.

Jaryd was also a groomsman at Jordan’s wedding in early 2024.

He was also by Jordan’s side when the AFL star made his debut for Sydney in 2017.

Like his brother, Jaryd also played football and is vice-captain of the Robe Roosters reserves side. He was a key member of the 2024 premiership-winning team, kicking seven goals in the grand final.

Jordan played five years for the Swans before moving to Adelaide at the end of 2021.

He quickly became one of the premier midfielders in the competition and was elevated to captain ahead of the 2023 season.

He also does significant work off the field for a number of different non-for-profit organisations.

Jordan is a board director for Ladder, the official charity of the AFLPA, and was announced as an ambassador for Childhood Cancer Association last month.

He also served as an ambassador for the Black Dog Institute, advocating for mental health awareness and resilience.

Jordan has played four games this season, missing the Round 3 loss to Geelong with a calf injury.

The Crows meet St Kilda at Adelaide Oval on Saturday night.
