ALAMEDA, Calif. (AP) The Oakland Raiders have activated safety Nate Allen from short-term injured reserve list in time for Sunday's game against Minnesota.

The Raiders waived receiver Marcus Thigpen on Saturday to make room on the 53-man roster.

Allen injured his knee in the season opener against Cincinnati. He is expected to start alongside Charles Woodson against the Vikings, with TJ Carrie moving back to cornerback.
