Roger Varian's charge won the Winner of the Prix Vermeille last September, and finished third to Yibir in the Breeders' Cup Turf in November. However, she was yet to make an appearance in the 2022 Flat season.
Varian posted on Twitter: "We are disappointed to report that Teona has met with a season-ending injury and will be retired. She was a pleasure to train and can now enjoy her second career as a broodmare."
The 18/1 shot Teona, under Olivier Peslier, stunned Oaks winner and hot favourite Snowfall in the Prix Vermeille.
Teona claimed the victory by a length-and-a-half, with La Joconde another half-length away in third. It was Snowfall's first defeat of the season.
Bred by Rabbah Bloodstock, Teona is a half-sister to the Group 2-winning Al Hilalee and is out of Pretty Polly Stakes winner Ambivalent. The four-year-old will now join Ali Saeed and his team for a career as a broodmare.
