ALAMEDA (AP) — The Oakland Raiders have signed cornerback David Amerson to a four-year contract extension.
Amerson joined the Raiders in September 2015 on a waiver claim from the Washington Redskins, where he played from 2013-15.
In 14 games for the Raiders last season, he set a single-season franchise record with 26 passes defensed to go along with career highs in tackles (62) and interceptions (four). Amerson also set a single-game franchise record when he had six passes defensed in a Nov. 29 win over the Tennessee Titans. He added his second career touchdown when he returned an interception 24 yards for the score in the season finale at Kansas City.
Amerson has played in 47 games with 35 starts, with 170 tackles (148 solo), six interceptions (two returned for touchdowns), 44 passes defensed and one forced fumble in three seasons with the Redskins and Raiders.
He was drafted by Washington in the second round (51st overall) of the 2013 draft.
