The BYU Cougars are mourning 22-year-old offensive lineman Sione Veikoso, who died in a construction accident in his hometown of Kailua, Hawai'i on Friday.

Six men were at the site when a 15-foot retaining rock wall behind a home partially collapsed and trapped three of them, according to the Honolulu Star-Advertiser. Veikoso was pronounced dead at the scene, his family confirmed to the newspaper, following emergency personnel clearing the rubble at the site.

“We are extremely saddened to learn of the tragic death of one of our brothers, Sione Veikoso,” Cougars head coach Kalani Sitake wrote on Twitter on Saturday. “His passing is heartbreaking to all of us. We offer our deepest condolences and prayers to his family as we share in their grief. Our love for you is forever, Sione!”
