Cam Newton has called Sunday's road game against the Buffalo Bills a "must win" for the New England Patriots.

The Patriots, who have lost three straight, are 2-4 and trail the Bills (5-2) in the AFC East.

"This is a must-win for us, and I'm going to control the things that I can control. I have two or three more days to prepare and that's what I plan on doing," Newton said.

The Patriots have won the division each of the past 11 seasons.

Julian Edelman underwent a precautionary standard knee procedure and will miss the New England Patriots' Week 8 game on Sunday.

Edelman has been limited all season because of his knee. Edelman leads the team with 21 receptions for 315 yards.

New England could be limited to Damiere Byrd, Jakobi Meyers and Gunner Olszewski at receiver for the game.

Cam Newton admitted his job as quarterback of the New England Patriots will be in jeopardy if he struggles like he did against the San Francisco 49ers. 

"The first thing I said to myself coming home was, 'You keep playing games like that, bro, and it's going to be a permanent change,'" Newton said Monday morning on Boston sports radio WEEI.

"You don't need to tell me that for me to understand that. I get it loud and clear."

Bill Belichick said he's "absolutely" sticking with Newton as his starter despite giving Jarrett Stidham some reps in the fourth quarter.

"For any type of competitor, do you feel embarrassed? Yeah," Newton said Monday in the radio interview. "I don't feel offended by what was done. I don't feel offended having this type of conversation. I'm a realist.

"I don't fear my position stability more so than controlling the locker room. Performances like yesterday jeopardizes [that]. It's like 'Oh my God!' Players talk and that's what's most important to me. Knowing you have your coaches' belief [is good], but my belief is that I want to have the whole facility ... It doesn't start with no miraculous play. It's a whole body of work that goes into performing on Sunday."

The New England Patriots had a positive COVID-19 test on Friday.

The Patriots are currently scheduled to play the Denver Broncos on Sunday in a game that was rescheduled from Week 5. The game is expected to be played despite the positive test.

The facility had been shut down Sunday, Monday and Tuesday, before players returned Wednesday for conditioning work. The team's first practice of the week was Thursday.

Cam Newton and Stephon Gilmore returned to practice for the first time since testing positive for COVID-19.

Both Newton and Gilmore are on track to play in Week 6 for the New England Patriots against the Denver Broncos.

Newton was activated from the reserve/COVID-19 list on Wednesday. Gilmore was activated from the list Thursday.

Both the New England Patriots and Tennessee Titans had no new positive coronavirus test results from the latest round Sunday, according to sources.

The Titans' Tuesday night game against the Buffalo Bills remains on as scheduled.

Tennessee plans to have a walk-through practice Monday -- similar to the types of workouts they would typically have on Saturdays, before a Sunday game day.

A positive test from the Patriots on Sunday led the NFL to postpone the Week 5 game between the Patriots and Denver Broncos that was scheduled for Monday.

The New England Patriots had one new positive COVID-19 test as of Sunday morning.

Their practice facility is being shut down again while further testing is conducted.

The Patriots are scheduled to play the Denver Broncos on Monday.

There was some good news regarding COVID-19 outbreaks on the New England Patriots and Tennessee Titans on Friday morning.

Both teams reported no new positive tests, a step towards seeing a full Week 5 schedule in the NFL.

The Patriots will continue to work remotely rather than report to their facility as they prepare to face the Denver Broncos on Monday night.

Things are a little more tenuous for the Titans, who haven't been able to open their facility in more than a week. They are currently in line to face the Buffalo Bills on Tuesday in a rescheduled game.

The NFL has moved Sunday's game between the New England Patriots and Denver Broncos to Monday.

The Patriots have not practiced and their facility was closed both Wednesday and Thursday after quarterback Cam Newton and cornerback Stephon Gilmore were moved to the team's reserve/COVID-19 list.

There were no new positive tests with the Patriots on Thursday.

The New England Patriots returned no new positive COVID-19 tests on Thursday morning.
