The Lions signed White to a one-year contract Saturday, NFL reporter Jordan Schultz reports.
White participated in all 17 regular-season games for the Raiders last year, producing 174 total tackles (including 2.5 sacks), three passes defensed (including one interception) and a forced fumble. The linebacker was ranked third in the NFL in tackles as well. White will provide a strong veteran presence to a Lions linebacker corps that has suffered consistent injuries over the past few seasons.
