San Francisco head coach Kyle Shanahan said Monday that Wallow will miss "at least a couple of weeks" due to a hamstring strain, Nick Wagoner of ESPN.com reports.
Shanahan seemingly ruled out the reserve linebacker through the 49ers' Week 8 bye, with Wallow expected to sit out Week 6 versus the Commanders as well as Week 7 in Atlanta. Wallow has accrued seven tackles (five solo) this season while seeing the majority of his playing time on special teams.
