Josh Rosen was active for two contests with the 49ers after being lifted from Tampa Bay's practice squad late in the season, but never saw the field. He should compete for Jimmy Garoppolo's backup spot, but it's still early in the game to know how that position will shake out.
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.
