Alexander Mattison has been ruled inactive for the Las Vegas Raiders' game against the Denver Broncos due to an ankle injury. With another running back, Zamir White, also sidelined, Ameer Abdullah is expected to take on the lead role in the backfield. Mattison's potential for a significant role was highlighted earlier in the season when he was performing efficiently compared to White, but injuries have hindered his contributions.

• Mattison's ankle injury has kept him out of action.
• Ameer Abdullah will likely lead the Raiders' backfield in his absence.
• Mattison's efficiency earlier in the season raises questions about his future role.
