Defensive coordinator Vic Fangio today said “it would be a stretch” if Chris Borland, who injured his ankle Sunday in Seattle, were able to play again this season. Borland, who leads the 49ers in tackles and was a legitimate candidate for rookie defensive player of the year, tried to come back into the game after his injury but limped off in frustration when his ankle didn’t respond.
The 49ers on Tuesday signed veteran linebacker Desmond Bishop to help make up the shortfall at inside linebacker. Bishop, who played at City College in San Francisco before going to Cal, said he’s been a 49ers fan his whole life and listed Lee Woodall as one of his favorites.
Bishop played six season under Green Bay defensive coordinator Dom Capers, who comes from the same coaching tree -- Jim Mora, Vince Tobin -- as Fangio. Therefore, the scheme and terminology that Bishop used with the Packers is similar to what Fangio uses in San Francisco.
Fangio said the team considered promoting practice squad linebacker Shayne Skov from the practice squad but that the front office decided on Bishop.
In other news, the 49ers added cornerback Cameron Fuller to the practice squad after another practice squad cornerback, Chance Casey, was signed to the Raiders active roster.
