Rookie backup Bailey Zappe threw for 309 yards and two touchdowns in his third NFL game, Bill Belichick tied George Halas for second on the all-time list with his 324th victory, and the New England Patriots buried the Cleveland Browns 38-15.

A person familiar with the Cleveland Browns' situation tells The Associated Press that quarterback Baker Mayfield didn't clear COVID-19 testing in time to be activated and play Monday, so third-stringer Nick Mullens will start against the Las Vegas Raiders.

The matchup between the Bengals and Broncos had no touchdowns scored in the first half.

Gifted two days by the NFL to maybe get healthier, the Browns prepared for a game they expected to play Saturday.

Only unvaccinated players and those experiencing possible symptoms of COVID-19 will be tested starting Sunday under the NFL’s revised protocols.

The Browns, who have nine players currently on the COVID-19 reserve list, will make the postseason for the first time since 2002 with a win. After learning of the positive tests, the team closed its facility for several hours to do contact tracing and Stefanski said players were doing virtual meetings — something that has become standard in 2020. "“I don’t think it would come as a surprise for a positive test in that market. The Browns did have a good development, with starting right guard Wyatt Teller cleared to practice after missing two games with a sprained ankle.

FILE - In this Sunday, Dec. 6, 2020 file photo, Cleveland Browns offensive tackle Jedrick Wills (71) takes the field for an NFL football game against the Tennessee Titans in Nashville, Tenn. Wills had been placed on the COVID list on Thursday, Dec. 24 after being in close contact with someone outside the team who had tested positive. The loss of Wills further depletes Cleveland's offensive line; starting right guard Wyatt Teller will miss his second straight game with a sprained ankle. In addition to Landry, the Browns will be missing receivers Rashard Higgins, Donovan Peoples-Jones and KhaDarel Hodge and linebacker Jacob Phillips. They were placed on the COVID-19 list on Saturday before the team flew to the New York area.

The Browns will try to earn a playoff spot without four wide receivers, including star Landry, their starting middle linebacker and his replacement due to COVID-19 protocols. But despite the six players being out, an NFL spokesman said Cleveland's game at the New York Jets will be played as scheduled on Sunday, Dec. 27. Cleveland's game against the New York Jets will be played as scheduled, an NFL spokesman said. Per league rules, Goodson will miss Sunday's game and the Jan. 3 matchup against Pittsburgh is also in question. Like numerous NFL teams, the Browns have been dealing with positive cases for most of the season.

The Lions (5-9) will also be without defensive coordinator Cory Undlin, defensive line coach Bo Davis, defensive backs coach Steve Gregory and linebackers coach Ty McKenzie against Tampa Bay (9-5) on Saturday. Browns first-year coach Kevin Stefanski said “there’s a possibility” when asked if Wills will play this week against the Jets. For the Lions, they will lean on two men to call plays for the first time in an NFL game. I’m calling plays in an NFL game.

They're thinking much bigger than all that after a dominant 20-6 win over the New York Giants on Sunday night. The victory got the Browns closer to clinching their first playoff spot since 2002, the NFL’s longest drought. New York's opening drive stalled at the 8 after McCoy's throw to Evan Engram fell incomplete in the end zone. It could've worked, too: Kicker Graham Gano was wide open in the end zone. The Browns came right back with a scoring drive capped by Mayfield's 2-yard pass to a wide-open Hooper in the back of the end zone early in the second quarter.

Cleveland Browns wide receiver Rashard Higgins (82) and quarterback Baker Mayfield celebrate after a 15-yard touchdown by Higgins during the first half of an NFL football game against the Indianapolis Colts, Sunday, Oct. 11, 2020, in Cleveland. (AP Photo/David Richard)CLEVELAND – Bill Belichick was their coach and Nick Saban on his staff the last time Cleveland Browns were this good this early. Just three years removed from 0-16, the Browns are 4-1 for the first time since ‘94 — Belichick’s fourth season. “We needed a play to be made — and I’m greedy when it comes to that.”On the Colts' next possession, Browns safety Sheldrick Redwine, who came in while Harrison was being evaluated for a concussion, picked off Rivers. Mayfield showed patience on his 2-yard scoring pass to Hunt, which gave the Browns a 10-7 lead early in the second quarter.
