NFL news updates: Kyle Shanahan talks 'lingering' calf issue for Christian McCaffrey

Fantasy and injury notes from around the league at conclusion of Week 1

Before Week 1 concluded, the San Francisco 49ers surprised the NFL world, particularly fantasy managers, with news of a calf strain to Christian McCaffrey. It was bothersome enough to sideline McCaffrey against the New York Jets. News broke of the injury about 90 minutes before kickoff in a game the Niners eventually won, 32-19.

Yahoo Sports has you covered with updates, news and notes from around the league as the season is now shifts to preparation for Week 2.

Let's start with the Niners' all-world running back.

The 49ers will have a short week to prepare for Sunday's game at the Minnesota Vikings. Is that enough time for McCaffrey to be ready to go or will Jordan Mason carry the rock again?

Head coach Kyle Shanahan wasn't definitive of McCaffrey's status for Week 2, but he did respond to an ESPN report that said there's a "real chance" that the running back wouldn't play next weekend.

"It's amazing. That person must be God," Shanahan said after the 49ers' victory against the Jets. "We just found out he wasn't playing today. I have no idea how he's going to feel tomorrow, or the next day. I thought he was playing this whole week until today. So I don't know who knows that he's not playing next week."

Of McCaffrey's leg injury, Shanahan also said: "It’s been lingering the last few weeks. But it’s getting better and better and hopefully it’ll be better next week.”

On Tuesday, Shanahan said that McCaffrey would have played versus the Jets had it been a playoff game. McCaffrey is currently listed as day-to-day. McCaffrey was limited in practice on Wednesday, too.

After a calf injury to Russell Wilson late in training camp put Justin Fields in the starting lineup for Week 1, the Steelers head into Week 2 with a question at quarterback after an 18-10 win at Atlanta in which Fields threw for 156 yards.

On Tuesday, head coach Mike Tomlin said the team is preparing Fields to be under center again and that Wilson will not practice fully on Wednesday. He added Wilson "feels better today than over the weekend."

Browns tight end David Njoku is considered "week-to-week," according to head coach Kevin Stefanski. Njoku suffered an ankle injury during Cleveland's blowout loss to Dallas. Cleveland.com's Mary Kay Cabot reported Tuesday that "he's expected to miss at least a couple of games."

  • Jordan Love may play for Packers

    After injuring his knee in their season opener in Brazil, Jordan Love may be able to play for the Packers this week after all.

    Green Bay head coach Matt LaFleur didn't rule Love out of their game against the Indianapolis Colts on Sunday. Love, however, still has to be cleared by the team's medical staff, but he doesn't need to practice in order to play. If he can't go, Malik Willis will take the field in his place.

  • CMC limited in practice for 49ers

    After missing their season opener as a late surprise scratch, Christian McCaffrey is practicing with the 49ers on Wednesday. McCaffrey will be limited in practice, however, and his status for Sunday's game against the Minnesota Vikings is still up in the air.

    Despite not having McCaffrey available, the 49ers had no issue getting past the New York Jets on Monday night. They cruised to a 32-19 win, and backup running back Jordan Mason racked up 147 yards and a touchdown on 28 carries.

  • Dolphins updates: Raheem Mostert out vs. Bills, De'Von Achane could play

    Dolphins head coach Mike McDaniel gave an update on two of the team's injured superstars on Wednesday.

    Running back Raheem Mostert is out vs. the Bills on Thursday after sustaining an unspecified chest injury during the Dolphins 20-17 win over the Jaguars.

    RB De'Von Achane injured his ankle against the Jags and McDaniel doesn't yet know if he'll be able to play.

    If the Dolphins decide to keep both Mostert and Achane out for Thursday's game, Jeff Wilson and rookie Jaylen Wright are the next up in the backfield.

  • Bills QB Josh Allen full participant Tuesday

  • Panthers place DT Derrick Brown on injured reserve

    Brown suffered a knee injury during Sunday's loss to the Saints. He will not return this season.

    "Definitely a huge loss, right? He's one of our best players. That's big shoes to fill," said Panthers head coach Dave Canales on Tuesday. "But at the same time, we've got players in there, I want them to know and be encouraged. If you go in, you play with great technique, and you just do your job, we don't need you to make the special plays that Derrick makes.

    "Just do your job, help the guys on either side of you and that's the truth of it. If you can play team football with a bunch of guys, you can have success."

    Brown, a 2023 Pro Bowler, set an NFL record for tackles by a defensive lineman in a season with 103 last year.

  • More details regarding Tyreek Hill being detained outside Hard Rock Stadium

    Per sources, Tyreek Hill received two citations as a result of his traffic stop Sunday: Careless driving and a seatbelt violation. Calais Campbell, who said after the game police told him they briefly placed him in handcuffs for "disobeying a direct order," did not end up receiving a citation. The Miami-Dade Police Department told me this morning that it remains an internal investigation so they cannot yet provide the details into what led to the citation for careless driving or why Hill was detained face-down on the ground in handcuffs. One of the officers on the scene remains on administrative duty.

    Hill was handcuffed outside Miami's Hard Rock Stadium just hours before the Dolphins kicked off against Jacksonville. Hill was eventually released and played in Miami's 20-17 victory.

    Hill told reporters after Sunday's game that he had "no idea" why he was detained. "Wasn't disrespectful because my mom didn't raise me that way. Didn't cuss," he said. "Still trying to figure it out."

    "I don't respect it, honestly," Lawrence said. "I get it, they want to see their team win. It's just a rough patch. It is what it is."

    Some fans even took to booing Daniel Jones as he exited the stadium following his performance that saw him go 22-for-42 with 186 yards and two interceptions.
