The NFL intends to play this weekend's Tennessee Titans-Pittsburgh Steelers game despite the fact that the Titans won't reopen their facility until at least Saturday after eight members of the organization tested positive for COVID-19.

While playing on Sunday remains the goal, the league has a contingency plan is in place to move the game to Monday night.

The Houston Texans do not plan to sign Earl Thomas, according to a source.

The free agent safety met with Houston and underwent a physical. Thomas had a workout scheduled, but it did not take place.

Bill O'Brien told Thomas' agents that the NFL required the Texans to cancel Thomas' workout because of COVID-19 concerns.

However, a source said the decision not to sign Thomas wasn't related to COVID-19.

Adrian Peterson will likely be the lead running back for the Detroit Lions for the foreseeable future.

Peterson had more snaps, rushes and yards than the rest of Detroit's running backs combined in Week 3.

The future Hall of Famer played 40 snaps in the Lions' 26-23 victory against the Arizona Cardinals on Sunday, getting 22 carries for 75 yards along with one catch for 10 yards.

"It's not anything that those guys are or aren't doing," Darrell Bevell said. "We're just trying to, again, accentuate their positives and put them in positions to be successful. You saw [D'Andre] Swift. His plays were a little bit down. We want to keep those up and get him more involved. The one play he catches, he has a nice catch-and-run, looks fast, looks explosive.

"It's just continuing to manage those guys and putting them in the best situations."

Mark Davis says the Las Vegas Raiders are looking into why several players were not wearing masks while attending a charity event held by Darren Waller that broke Nevada rules for the coronavirus pandemic and might have violated NFL regulations.

The Darren Waller Foundation held a fundraising event Monday at the DragonRidge Country Club in the Las Vegas suburb of Henderson. Players were seen on video without masks at the indoor event while talking and mingling with guests, who also weren't wearing masks.

"Guys have to be more stringent in fighting the virus," Mark Davis said. "It's still our toughest opponent."

The city of Henderson fined the DragonRidge Country Club $2,000 on Tuesday for four violations of the Nevada governor's COVID-19 emergency directives, including people not wearing masks and having more than 50 people at the event.

The Tennessee Titans had three new player positives and five new personnel positives for COVID-19 on Monday, according to sources.

The Titans and Minnesota Vikings, who hosted them on Sunday, have suspended in-person club activities.

Tennessee is scheduled to play the Pittsburgh Steelers in Week 4.

ESPN's Dianna Russini reported that the Titans will be shut down until Saturday.

The Houston Texans had a "batch" of false positive COVID-19 tests prior to Sunday's game against the Pittsburgh Steelers.

The report did not indicate when the false positives occurred, but subsequent retests were negative and no player missed Sunday's game for testing reasons.

Players are tested daily, including a "pregame" test the morning before the game. Before the beginning of the season, the NFL implemented a new protocol that accelerated the process of identifying false positives.

Chris Carson has a first-degree knee sprain and Pete Carroll is upset over the play on which the injury occurred.

Carson was hurt in the fourth quarter of the Seattle Seahawks' 38-31 victory over the Dallas Cowboys when defensive tackle Trysten Hill executed a gator-roll tackle. He brought down Carson from behind and, with both players on the ground, continued to hold on to the running back's left leg while rolling over.

"Yeah, I was really pissed about that one," Carroll said. "I don't know what's going to happen with that, but I was pissed because that guy hurt him, unfortunately."

Mike McCarthy defended Hill on Monday.

"By no means do we want to see a player hurt, but trust me, there was zero intent involved there," McCarthy said.

Carson is currently considered week-to-week.

The Baltimore Ravens lost for the first time in 15 regular season games on Monday night against the Kansas City Chiefs.

Asked how the Ravens can get over the hurdle of beating the Chiefs, Lamar Jackson interjected by saying: "Our kryptonite."

Jackson is 0-3 against the Chiefs after passing for a career-worst 97 yards. He's 21-1 against the rest of the NFL in the regular season.

The Houston Texans are likely to sign Earl Thomas.

The Baltimore Ravens released Thomas in August after he had an on-field altercation with teammate Chuck Clark. Thomas allegedly punched Clark during practice.

On Monday, the Texans put safety A.J. Moore on injured reserve with a hamstring injury, although he is expected to return later this season.

Adam Gase is under more intense scrutiny this week as the New York Jets get off to a slow start to 2020.

The Jets play the Indianapolis Colts on Thursday Night Football, which could be a pivot point for whether he retains his job.
