8:30 a.m. ET: A full slate of NFL games features plenty of big question marks on the injury front.

Sunday's Week 4 schedule kicks off at 9:30 a.m. ET with the New York Jets battling the Miami Dolphins at Wembley Stadium in London. The big names all will be in action for that one, as Jets running back Chris Ivory (quad) and wide receiver Eric Decker (knee) both are active.

The status of some other stars, however, remains unclear. Indianapolis Colts quarterback Andrew Luck (shoulder) still is questionable for Sunday's contest, while Seattle Seahawks running back Marshawn Lynch (hamstring) still is a question mark for Monday night's game against the Detroit Lions.

As always, keep it here for the latest injury updates from around the league as they happen.
