Scotland midfielder Scott McTominay missed the team bus to their Boston hotel after an upset stomach ruled him out of Thursday's training. The Napoli player traveled separately with a doctor, believed to be a precautionary measure, as Steve Clarke's squad prepare for their World Cup opener.

Scotland begins their first World Cup campaign in 28 years on Saturday against Haiti at Boston Stadium, followed by matches against Morocco and Brazil. McTominay's availability remains uncertain after his recent goal helped secure a 4-0 victory over Bolivia.

Teammate Kenny McLean acknowledged the concern at Thursday's press conference, saying everyone knows how important McTominay is to the squad. The 29-year-old has contributed 15 goals across 70 caps for Scotland.

McTominay's potential absence would significantly impact Scotland's midfield options for a crucial group stage opener against Haiti, with Clarke expected to provide an update on Friday.
