The Seahawks signed rookie running back Ronnie Rivers on Wednesday, adding backfield depth ahead of their final preseason game.
Linebacker Jon Rhattigan was placed on the reserve/physically unable to perform list to make room on the 80-man roster.
Rivers, who went undrafted out of Fresno State this year, initially signed with the Cardinals as an undrafted free agent, then was waived earlier this month as Arizona reduced its roster from 90 to 85 players.
During his Fresno State career, Rivers set school record for career touchdowns (52), rushing touchdowns (40), as well as receptions (150), receiving yards (1,417) and receiving touchdowns (12) by a running back. He also ranks third in school history with 3,417 career rushing yards.
Rivers is the son of former NFL running back Ron Rivers, who also played at Fresno State before going on to spend five seasons with the Lions and one with the Falcons from 1995-2000.
Rhattigan, who made the team as an undrafted rookie last year, suffered a season-ending knee injury late last season. Rhattigan opened camp on the active/PUP list, meaning he could return at any time but did count against the roster limit. By moving Rhattigan to the reserve/PUP list, the Seahawks open up a roster spot, but it also means Rhattigan has to miss at least the first four games of the regular season before he can return.
