Whom should you start? Whom should you sit? To help you set your fantasy football lineups and avoid starting an offensive player who won't be in the lineup, we'll post fantasy-relevant updates and analysis here as NFL teams release their official inactives lists.
Official Sunday inactives should begin coming in approximately 90 minutes before the scheduled kickoff times: around 11:30 a.m. ET for the early games and 2:30 p.m. ET for the late-afternoon games.

What we were watching for late
Marvin Mims Jr., WR, DEN (thigh): He was removed from the injury report late in the week and, as expected, is active today. He should be the team's No. 2 WR option behind Courtland Sutton.
Jayden Reed, WR, GB (foot): He was limited in practice this week, but given that it's Week 1, we're not surprised to see him active. Dontayvion Wicks and Savion Williams were both questionable headed into Sunday. Even though both of those receivers are also active today, rookie Matthew Golden might still be in line for a big debut.
Christian McCaffrey, RB, SF (calf): Given his injury history and a missed practice on Friday, it's understandable why fantasy managers might have been wary. That said, McCaffrey said he's feeling great and early-morning reporting said he would play. Indeed, he is active. Isaac Guerendo (shoulder) and Jordan James (finger) both enter the season banged up. Brian Robinson Jr. is the only other healthy RB on the team.
Ruled out prior to Sunday
Isaiah Likely, TE, BAL (foot): Starter Mark Andrews will still get the majority of TE looks, with Charlie Kolar getting the scraps.
Tyler Bass, K, BUF (hip/groin): He has been placed on IR. Matt Prater will handle Buffalo's kicking duties.
Quinshon Judkins, RB, CLE: He signed with the team only on Saturday after off-the-field legal issues had delayed the process. Expect Dylan Sampson and Jerome Ford to split backfield work in Week 1.
Christian Kirk, WR, HOU (hamstring): Kirk might be out of action for a few weeks. Braxton Berrios (hamstring) is also out for Week 1, so rookies Jayden Higgins and Jaylin Noel should both be tasked with a larger-than-expected workload right out of the gate.
Jaylen Wright, RB, MIA (knee): De'Von Achane will be backed up by rookie Ollie Gordon II and Jeff Wilson Jr., who was elevated to fill in for Wright.
Darren Waller, TE, MIA (hip): The veteran is not yet ready to shake off his retirement cobwebs. Julian Hill and Tanner Conner will share whatever TE targets there are to be had.
Chase Young, LB, NO (calf): This certainly could benefit any Cardinals in your starting lineup.
Jake Bobo, WR, SEA (concussion): This frees up rookie Tory Horton for work as the team's No. 3 WR.
Chris Godwin Jr., WR, TB (ankle): Not expected back until at least Week 5.
What we were watching for early
Kyler Murray, QB, ARI (illness): ESPN's Adam Schefter reports that although Murray is being added to the team's injury report, he is active and all expectations are that the quarterback will still be able to start today's game.
Darnell Mooney, WR, ATL (shoulder): He saw only limited practices this week, so it's not a shock that he's inactive today. With him sitting out, Casey Washington might be an interesting flier.
Tyler Goodson, RB, IND (elbow): DJ Giddens will likely spell Jonathan Taylor (if needed) with Goodson officially not suiting up.
Malik Nabers, WR, NYG (back): He was not listed on the team's injury report and he'll almost certainly start. Just be aware that there's a chance that his "little tightness" could flare up during the game.
