The 49ers officially announced Friday afternoon that they have reached across the Bay to sign ex-Raiders RB Rock Cartwright to a one-year deal. Terms of the deal were undisclosed.
"Rock has been a standout special-teams contributor, who has also shown versatility at the running back position," 49ers GM Trent Baalke said. "He has all of the intangibles that we look for in a 49er."
Originally a seventh-round choice (257th overall) by the Redskins in the 2002 NFL draft, the 10-year veteran spent his first eight seasons with the Redskins (2002-09), before playing the past two with the Raiders (2010-11). In his career, Cartwright has played in 154 games (five starts), recording 228 carries for 956 yards and six touchdowns. A key special-teams contributor, he has returned 231 kicks for 5,450 yards (23.6-yard average) and one touchdown, in addition to making 93 tackles on those units.
The way we see it
Cartwright replaces special-teams ace Blake Costanzo and then some because of his versatility, which Costanzo, who signed with the Bears, lacked. In his two years in Oakland, Cartwright had only 18 touches (13 carries, five receptions). But he at least poses a threat in a creative Niners ground game with a lot of moving parts.
