Hasty (ankle) didn't practice Wednesday, Matt Maiocco of NBC Sports Bay Area reports.
Hasty has largely seen playing time in obvious passing situations, of which there were few in Monday's 31-10 win over the Rams. His absence didn't have much affect on the game, but it freed up some extra snaps for Jeff Wilson, who could now take on a larger role if Hasty is out again and Elijah Mitchell has any limitations after undergoing finger surgery Tuesday.
