Hasty was trending in the wrong direction over the last few weeks, and his injury means he can be dropped in typical leagues. With Raheem Mostert, Jeff Wilson and Tevin Coleman out, it should mean a big workload for McKinnon going forward, at least until Mostert is able to return. Fullback Juszczyk could get more involved and Walter is a name to keep an eye out for despite being at the bottom of the depth chart.
Not a surprise as Coleman left Week 8 early after just returning to the lineup. Sources say Walter will be promoted to the roster from the practice squad, but most of the work should go to Hasty and McKinnon on Thursday night against the Packers. With Jimmy Garoppolo and George Kittle also out, fantasy output may be hard to come by for 49er plays.
