Write a question about the following article: Following the 28-23 victory on Thursday Night Football against the Panthers, the Eagles returned home for the next 3 games and were once again in a prime time matchup; this time, a Monday Night matchup against the Washington Redskins. The Eagles started off the game in sluggish fashion, and after being backed up over 20 yards due to penalties on their first drive of the game, Carson Wentz threw his 4th interception of the season. After exchanging field goals, Redskins running back Chris Thompson caught a 7-yard touchdown pass from quarterback Kirk Cousins. Wentz and the Eagles responded with an offensive outburst to end the first half. Wentz found rookie wide receiver Mack Hollins for a 64-yard touchdown, and later found tight end Zach Ertz for a four-yard strike to end the first half. The Eagles increased their lead to 24-10 early in the third quarter, with Wentz finding rookie running back Corey Clement on a beautiful throw in the corner of the end zone. The Redskins responded at the end of the third, with Kirk Cousins finding tight end Jordan Reed for a five-yard touchdown. Once again, Wentz led the Eagles down the field, capping of the drive with a 10-yard touchdown to Nelson Agholor. A Jake Elliott field goal later in the quarter opened the lead to 34-17, and the Eagles went on to win 34-24. Wentz once again was in MVP form, completing 17/25 attempts for 268 yards and 4 TDs. However, the win came at a cost, as future Hall of Fame left tackle Jason Peters was lost for the season with a torn ACL, and starting middle linebacker Jordan Hicks was also lost for the season with a ruptured achilles. With the win, the Eagles improved to 6-1 and swept the Skins for the first time since 2013.
