After Rehn, 29, announced that she had chosen Sutter, 27, as the winner, he proposed marriage on bended knee just six weeks after meeting the former Miami Heat cheerleader.
"You stepped out of my dreams and into my world," Rehn told Sutter on ABC. "My walls have finally crumbled, and I can now tell you without reservation that I am in love with you."
Sutter, a fifth-round selection of the Ravens in 1998 who was released in training camp, has been working as a firefighter in Vail, Colo., since brief stints with the Carolina Panthers and Seattle Seahawks.
Sutter reportedly has drawn recent interest from the Winnipeg Blue Bombers of the Canadian Football League.
Apparently, Sutter's idea of asking Rehn's father for his blessing beforehand was the final trump card in being declared the winner of the reality television series.
