The Lions placed TE Sam LaPorta on IR with his back injury. He's out through at least through Week 14, and it's unclear if he'll be ready to return when first eligible in Week 15. We still don't have any details on this back injury. LaPorta is worth trying to hang on to in fantasy leagues, but he's not a must-hold if you need the roster space. TE Brock Wright is next up on Detroit's depth chart but owns just 65 catches in 67 career games. TE Ross Dwelley -- 45 catches in 108 games -- is also on the active roster. TEs Anthony Firkser and Zach Horton are on the practice squad. We wouldn't bother with any of these guys in fantasy right now. Expect most of LaPorta's targets to be spread to WRs Amon-Ra St. Brown and Jameson Williams and RBs Jahmyr Gibbs and David Montgomery.

The forecast for tonight's Colts-49ers game calls for a 100% chance of rain with winds of 20-30 mph. That's ugly -- and certainly enough to impact the passing and kicking games. We'd try to avoid both of these passing games outside of 49ers WR Deebo Samuel and Colts WR Michael Pittman. You should also stay away from both Ks.

49ers TE George Kittle (calf) is listed as doubtful for Sunday’s game vs. the Cardinals. It’s a surprise after he played through the calf injury last week. The ‘Niners are holding out some hope that he’ll be able to play, but Kittle should be on fantasy benches for now. Ross Dwelley is San Francisco's backup TE.

SI's Grant Cohn reports that 49ers TE George Kittle has caught just 2 passes through 5 days of camp. "Instead they're using him as a blocker and a decoy while they call passes for Brandon Aiyuk, Deebo Samuel and Ross Dwelley," Cohn writes. That does seem odd given the financial commitment to Kittle. We'll go ahead and give HC Kyle Shanahan the benefit of the doubt and assume he has not converted Kittle to decoy/blocker. But Kittle's early-round draft position makes this situation worth keeping an eye on -- especially given that San Francisco is bringing along a rookie QB. It's tough to imagine the Niners getting too cute just to try to hide that they like Kittle.
