49ers injury alert:
Tight end George Kittle has a groin issue and won't practice today.
Related players: Tyler Kroft, Ross Dwelley
Fantasy Impact:
The tweet quoted Shanahan as saying he, "Was hoping [Kittle would] be good today, did little Monday, we’ll have to see day by day." Owners will want to monitor this leading up to Sunday. Kroft and Dwelley are up next on the depth chart. The 9ers do have an early game at Chicago in Week 1 so owners will be able to adjust.
