49ers place Ian Williams on I.R., sign Owen Marecic

The 49ers just announced they’ve placed injured nose tackle Ian Williams on the injured reserve list. To replace his roster spot, the 49ers have signed free agent and former Stanford fullback Owen Marecic.

It’s worth noting 49ers’ starting fullback Bruce Miller has struggled the first two games of this season according to Pro Football Focus. They’ve given him a -2.1 run blocking grade and a -0.8 pass blocking grade through two games. If he continues to struggle, he could lose playing time to Marecic.
