Cyle Larin, the Championship's top scorer with seven goals in eight matches, has returned early to Southampton after withdrawing from Canada international duty with a back irritation, raising doubts over his availability for Sunday's south coast derby against Portsmouth.

What happened on international duty

Canada released a statement confirming the striker was struggling with the issue before their friendly against Peru over the weekend. Larin took no part in the match itself, sitting as an unused substitute as Jesse Marsch's side beat Peru 2-0 in Montreal. He has since returned to St Mary's for further evaluation.

The timing lands at a particularly sensitive moment for Southampton. A player carrying seven goals in the first eight fixtures of the season is not someone any manager wants second-guessing fitness in the days before a derby. The club will now monitor him closely before naming their squad for Sunday's fixture.

Peretz also returns injured

Larin is not the only Southampton player to come back from the international window with a concern. Goalkeeper Daniel Peretz withdrew from Israel duty on Friday with a minor injury of his own. Southampton are therefore assessing two players simultaneously ahead of what promises to be one of the most charged fixtures on their calendar.

The club have given no timeline on either player's return to full training, and further evaluation will determine whether both are available to face Portsmouth.

What Larin's absence would cost

Seven goals from eight Championship appearances places Larin comfortably clear at the top of the division's scoring charts at this early stage of the campaign. His movement across the front line and instinct inside the box have made him central to Southampton's attacking structure. Any spell on the sidelines, even a short one, removes the focal point that the rest of the forward line organises itself around.

A back irritation is not the same as a structural injury, and the fact that Larin was fit enough to travel to Montreal and sit on the bench suggests this is being managed cautiously rather than treated as an emergency. Still, back problems can tighten unpredictably, and Southampton will not rush a decision that risks making matters worse with a high-intensity derby on the horizon.

Sunday's derby in focus

Portsmouth visit St Mary's on Sunday in a fixture that carries enormous local significance. Southampton will be anxious to field their strongest possible side, and the fitness of both Larin and Peretz will be the key storylines to track through the remainder of the week. The club are expected to provide a further update closer to the match.
