Branch, 27, suffered a broken leg in Oakland’s Week Two win vs. Jacksonville and has not played since. He’s recorded more than 100 tackles in three different seasons since joining the Raiders out of Connecticut in 2008.
To take Branch’s roster spot, the Raiders promoted defensive tackle Ricky Lumpkin from their practice squad. A Kentucky product, the 25-year-old Lumpkin had been on the Raiders’ practice squad since Nov. 20.
Lumpkin is being added to the Raiders’ roster almost a year to the day that he appeared in his first NFL regular-season game as a member of the Cardinals. He entered the NFL with Arizona in 2011.
