Mattison (ankle) is listed as questionable for Sunday's game in Tampa Bay, Paul Gutierrez of ESPN.com reports.
For a second straight week, Mattison has operated with a cap on his reps and ended it as questionable to suit up. He ultimately was inactive last Friday at Kansas City, but if he returns this weekend there's a chance he'll retake control of the Raiders backfield from Ameer Abdullah and Sincere McCormick, with Zamir White (quadriceps) still sidelined.
