Buchanan tweaked his hamstring and left the Canada camp as a result, but the injury isn't considered serious, according to Canadian Soccer Daily.
Analysis:Further exams will happen once Buchanan returns to Villarreal, but now there's clarity on the issue that made him depart the NT camp in the first place, and he should be considered doubtful to face Real Madrid on Saturday. The winger has yet to record a goal or an assist for Villarreal this season, but he's racked up 11 shots, eight chances created and 24 crosses in his seven appearances.
