After suffering a hamstring injury during Wednesday's practice, he was not on the field Friday as the team continued preparing for the Cincinnati Bengals.According to KPRC2's Aaron Wilson, Collins is dealing with a Grade 1 hamstring strain and is not expected to play on Sunday.Collins isn't the only wide receiver at risk of missing Week 2. Both Lamar Jackson and Justin Herbert each could be without key weapons on Sunday.In Baltimore, Ravens wideout Zay Flowers left a Week 1 win over the Indianapolis Colts with a hamstring injury. That issue had kept him out of practice all week after head coach Jesse Minter had labeled him day-to-day, but he was back on the field on Friday. Jackson will already not have Ja'Kobi Lane as a target after the rookie was placed on injured reserve following wrist surgery.Ladd McConkey was at Los Angeles Chargers' practice on Thursday, but working off to the side. The wide receiver suffered a rib injury during their Week 1 loss to the Arizona Cardinals and was also said to be day-to-day.Other receivers at risk of missing Week 2 include Chris Olave (hamstring) of the New Orleans Saints and Brian Thomas Jr. (shoulder) of the Jacksonville Jaguars.Cooper Rush will start again for the Atlanta Falcons with Jack Strand backing him up. Tua Tagovailoa is not fully recovered from the oblique injury that kept him from playing in Week 1 and Michael Penix Jr. (ACL) is "close" to returning, but has been ruled out.Other Week 2 injuries to monitor: Kyler Murray (concussion) was limited during Thursday's practice after suffering a concussion in Week 1 against the Green Bay Packers. If the Minnesota Vikings quarterback is not cleared in time, Carson Wentz will get the start against the Chicago Bears.New England Patriots running back TreVeyon Henderson (ankle) will play Week 2 against the Steelers, he told reporters on Thursday. Henderson missed the opening game with an ankle injury suffered during training camp.Same goes for New Orleans Saints back Alvin Kamara. The veteran sat out Week 1 with a knee sprain, but also declared himself fit to play against the Ravens this week. "I'm going," Kamara said. "If it wasn't right, I wouldn't be in. I feel great, moving well, really no limitations. I feel good." It remains to be seen if Week 2 will be the final game that Brock Bowers (knee) misses after having surgery to repair his meniscus. The Las Vegas Raiders tight end was set to miss 1-2 games after sitting out the opener. He was on the field for Friday's practice.Here's the rest of the Week 2 injury report (players will be added as teams release their reports):ARIZONA CARDINALSATLANTA FALCONSQB Michael Penix Jr. (ACL): OUTG Chris Lindstrom (concussion): questionableCB A.J.
