Dwelley (ribs) didn't practice Thursday, Matt Barrows of The Athletic reports.
Dwelley sat out the team's first practice ahead of Monday's showdown with the Rams due to a rib issue. The extent of the injury remains unclear, but he'll have two more opportunities to practice before the team needs to make a decision on his status. With George Kittle back in the mix, Dwelley saw just four offensive snaps in Week 3, so his potential absence wouldn't be major loss to San Francisco's offense.
