Overview
- Collyer left after 11 minutes of his third start in a 1-1 draw with Birmingham City at The Hawthorns.
- Ryan Mason said it is a muscle issue that looks like a hamstring problem and the club will assess him in the next couple of days.
- He will miss Saturday’s home match against Swansea City, with the length of his absence currently unknown.
- The 21-year-old previously suffered an October injury against Preston that sidelined him for about a month and Wednesday was his first start since returning.
- On a season-long loan from Manchester United, Collyer has a history of muscle issues that prompted a cautious reintegration, and Mason noted the setback underscores squad depth needs after a recent midfield suspension.
