Southampton have confirmed that right-back Valentino Livramento has sustained an ACL injury and is set to be sidelined for the rest of 2022.
The 19-year-old was forced off on a stretcher midway through the first half of the Saints' 2-2 draw at Brighton & Hove Albion last weekend, following a collision with Enock Mwepu.
Southampton have now revealed on their official website that Livramento will undergo surgery on his knee before beginning a period of rehabilitation.
A definitive timescale has not been put on the defender's return, but the Saints have stated that he is likely to miss the rest of 2022.
Livramento has enjoyed an impressive first season at St Mary's since moving from Chelsea last summer and has become a first-team regular under Ralph Hasenhuttl, starting 27 of his 32 appearances across all competitions.
Kyle Walker-Peters has predominantly operated at left-back this term due to Livramento's form on the right, but the former is now the most likely candidate to play at right-back for the foreseeable future, with Romain Perraud on the opposite flank.
