Mattison (ankle) was a limited practice participant Wednesday, Paul Gutierrez of ESPN.com reports.
Fellow running back Zamir White (quadriceps) was a non-participant and thus appears more likely than Mattison to miss a third straight game this Sunday in Tampa. Ameer Abdullah filled in as the starting back the past two weeks, but Sincere McCormick had a significant role in the second game, taking 38 percent of snaps and a team-high 12 carries (for 64 yards) in the 19-17 loss to Kansas City last Friday. It's difficult to project how large Mattison's role will be if he returns to action this Sunday, considering he's averaging 3.3 yards per carry this season and has reached 40 rushing yards in just one of his five starts. He's also on an expiring contract, which could be enough reason for the Raiders to open up more work for McCormick, a third-year player whom Las Vegas will be able to retain heading into 2025 as an exclusive-rights free agent.
