Hasty (ankle) was a non-participant at Thursday's practice, Jennifer Lee Chan of NBC Sports Bay Area reports.
Hasty has been dealing with ankle injuries for much of the season, missing four games to date (including Monday's win against the Rams). He's been joined on the sidelines this week by Elijah Mitchell, who is recovering from a procedure on a broken finger. Mitchell seems to be trending toward playing Sunday at Jacksonville, so if Hasty is unable to suit up Jeff Wilson will be the main complementary option out of the 49ers backfield.
