The Giants placed Furman on the 10-day injured list Friday due to a right oblique strain, retroactive to Wednesday.
Furman will be eligible to return from the IL for San Francisco's final two regular-season games, but with the Giants out of the race for a wild-card spot, they likely won't be in a rush to bring him back. Victor Bericoto (knee) was activated from the injured list to take Furman's place on the 28-man roster.
