Hasty (ankle) is cleared to return for Sunday's game in Seattle, with no designation on the 49ers' final Week 13 injury report, Nick Wagoner of ESPN.com reports.
Hasty has now missed six games with ankle injuries (Weeks 3-6, 10-12) and worked as San Francisco's passing-down specialist in the five others. The role has mostly gone to Kyle Jusczyk when Hasty's been out, though Jeff Wilson is also capable. In any case, Hasty is averaging only 2.6 carries and 2.6 catches for 27.8 yards per game, with his usage topped by that of early down back Elijah Mitchell (17.9 carries, 1.8 catches per game).
