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

Cleveland Browns quarterback Baker Mayfield (6) celebrates with teammate Austin Hooper (81) after they connect for a touchdown during the first half of an NFL football game against the New York Giants, Sunday, Dec. 20, 2020, in East Rutherford, N.J. (AP Photo/Seth Wenig)EAST RUTHERFORD, N.J. – Baker Mayfield led two 95-yard touchdown drives and the Cleveland Browns moved closer to ending their 17-year playoff drought with a 20-6 victory over the New York Giants on Sunday night. Mayfield was sharp all night, helping the Browns (10-4) bounce back from a 47-42 loss to Baltimore last Monday night. The win 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 Chargers and Falcons are tied at 17 midway through the fourth quarter. Kenny Moore also starred for the Colts with a spectacular one-handed, diving end-zone interception in the second quarter. Adams didn’t do much other than run the scrambling Darnold to the sideline midway through the second quarter. Seattle took its opening possession and got 19-yard touchdown pass from Russell Wilson to Freddie Swain. Mack also recovered a Duke Johnson fumble in the first quarter and deflected a Watson pass in the second quarter.

The NFC East-leading Philadelphia Eagles have gotten healthier on offense in time for another division game. Wide receiver Alshon Jeffery is back in Philadelphia’s lineup against the New York Giants, his first action since foot surgery last year. Running back Miles Sanders, the Eagles' leading rusher, is also back after missing three games with a knee injury. Okung will miss his fifth game this season because of injury, so Dennis Daley starts, protecting Teddy Bridgewater’s blindside. The Buccaneers are playing without left guard Ali Marpet, who will miss his second consecutive game with a concussion.

(AP Photo/David Richard)CLEVELAND – Bill Belichick was their coach and Nick Saban was on his staff the last time the Cleveland Browns were this good this early. On the Colts' next possession, Browns safety Sheldrick Redwine, who came in while Harrison was being evaluated for a concussion, picked off Rivers. The defense bowed up in the second half and played well enough to win. Mayfield showed patience on his 2-yard scoring pass to Hunt, which gave the Browns a 10-7 lead early in the second quarter. Rookie LB Jacob Phillips injured his knee in the second half.
