Leeds Rhinos centre Harry Newman will go for a scan on Monday to determine the extent of a hamstring injury which forced the centre from the field in Sunday's pre-season clash with Hull FC.
Newman was withdrawn midway through the first half of the 38-6 win against the Black and Whites and headed straight down the Headingley tunnel for assessment.
He didn't return for the remainder of the game, and Leeds assistant coach Sean Long confirmed the Rhinos now face a nervous wait to discover just how serious the injury is.
