Head coach Kyle Shanahan said the team will not know Kittle's status until the end of the week. The 49ers play on Monday night, so their final injury report won't come out until Saturday. Kittle would be a big loss for the 49ers going into a huge NFC West showdown with the Seahawks. You might want to check into backup options now just in case Kittle can't go so you're prepared, though the Monday night kickoff does throw a minor wrench into those plans. Check back Friday and Saturday on Kittle's progress.
