Input: Looking to be over .500 for the second time this season, Washington returned home to face the 4-0 Atlanta Falcons, in hopes of snapping a 7-game home losing streak, as well as, as previously mentioned, be over .500 for the first time since Week 1. A game that was billed to be a game with lots of offense, and little defense, ironically had the script flipped on its head. In the first quarter, neither team was able to threaten the other, and the teams played to a scoreless tie, with both teams struggling to get the offense in its normal rhythm. In the second quarter, Falcons quarterback Matt Ryan threw an interception to Redskins linebacker Ryan Kerrigan who returned it for a Redskins touchdown. After an Atlanta three-and-out, Washington got into the red zone, but Redskins kicker Billy Cundiff, who had missed three field goals the week before in Tampa Bay, shanked one from 31 yards out, and Washington was unable to build upon its advantage. Subsequently, the Falcons got the ball back, and Matt Ryan was able to find legendary tight end Tony Gonzalez to even the score at 7-7. In the third, defenses continued to set the tone. On its second possession of the second half, Washington moved the ball effectively into the red zone. However, on third down, Redskins quarterback Robert Griffin III scrambled to the left, slid down, and was hit hard by Falcons linebacker Sean Weatherspoon, and left the game with a concussion, and did not return. Cundiff gave Washington a 10-7 advantage by booting a 23-yard field goal, but Washington's main concern now was the health of their quarterback. In the fourth, Washington's defense, who had been on the field far more than it had been off, began to wear down. Matt Ryan found Julio Jones in the corner of the endzone to give Atlanta its first advantage of the day, at 14-10. However, the Redskins, in spite of an injured Griffin, fought back. Fellow rookie Kirk Cousins entered the game and, on 3rd-and-9, found a wide open Santana Moss for a 77-yard strike to put Washington back in the lead, at 17-14. On Atlanta's ensuing possession, veteran kicker Matt Bryant evened the score at 17-all. After a Washington punt, Ryan got the ball back. With a now-exhausted Redskins defense on the field again, Ryan picked the Redskins defense apart, then watched his running back, Michael Turner gash Washington and reach the endzone, and gave Atlanta a 24-17 lead. On Washington's ensuing possession, they were able to get to Atlanta's side of the field, but Cousins showed his rookie colors, stared down a receiver, and veteran cornerback Dunta Robinson made him pay, intercepting him. After Washington's defense stood tall, Washington got one final chance at it. However, Cousins was intercepted again on its first play of the ensuing drive, this time by Thomas DeCoud, sealing the win for Atlanta. Atlanta improved to 5-0. With the loss, Washington fell to 2-3 and lost their eighth consecutive home game. They have not won at home since their Week 2 win over the Arizona Cardinals last season. After the game, Washington was fined $20,000 for not updating Robert Griffin III's status.

Input: Open warfare broke out in 1352, when John V, supported by Venetian and Serbian troops, launched an attack on Matthew Kantakouzenos. John Kantakouzenos came to his son's aid with 10,000 Ottoman troops who retook the cities of Thrace, liberally plundering them in the process. In October 1352, at Demotika, the Ottoman force met and defeated 4,000 Serbs provided to John V by Dushan. This was the Ottomans' first victory in Europe and an ominous portent. Two years later their capture of Gallipoli marked the beginning of the Ottoman conquest of the Balkans, culminating a century later in the Fall of Constantinople. Meanwhile, John V fled to the island of Tenedos, from where he made an unsuccessful attempt to seize Constantinople in March 1353. John VI Kantakouzenos responded by having Matthew crowned as co-emperor, but John V Palaiologos, enlisting Genoese support and relying on the declining popularity of Kantakouzenos, succeeded in entering the capital in November 1354. John VI Kantakouzenos abdicated and retired to a monastery. Matthew held out in Thrace making war upon the Serbs in 1356. Then Matthew gathered an army of 5,000 Turks and marched on Serres the Serbian held capital of John Ugleisha.
