Raiders' Alexander Mattison: Limited in practice

Mattison (ankle) was a limited practice participant Wednesday, Paul Gutierrez of ESPN.com reports.

Mattison looks to be healthier than fellow Raiders running back Zamir White, who hasn't practiced since suffering a quadricep injury Week 11. Mattison injured his ankle later in the same game and then missed the Week 12 loss to the Broncos, allowing Ameer Abdullah to play 88 percent of snaps in that contest. Mattison could be back in the lead role if he's active for Friday's game against the Chiefs.
