Raiders sign LB Horace Miller, WR Milton Williams III

ALAMEDA, Calif. -- The Oakland Raiders have signed free-agent linebacker Horace Miller and re-signed wide receiver Milton Williams III.

The Raiders waived cornerback Travell Dixon and receiver Austin Hill on Wednesday to make room on the roster.

Miller spent training camp last summer with Seattle and then was signed in October to Carolina's practice squad. He spent one week on Carolina's active roster in December, but did not play in a game. He was waived by the Panthers in April.

Williams rejoins the Raiders after a brief stint with the team earlier this month.
