Input: Hoping to rebound from their last-second home loss to the Panthers, the Chargers flew to Invesco Field at Mile High for a Week 2 AFC West duel with the Denver Broncos. In the first quarter, San Diego trailed early as FB Michael Pittman getting a 1-yard TD run, after a Philip Rivers pass to Chris Chambers was ruled an interception on the field. The Chargers challenged the ruling, but the replay system was inoperative to the officials, so the ruling on the field stood. The 'Bolts would respond with kicker Nate Kaeding getting a 34-yard field goal. In the second quarter, Denver increased its lead with QB Jay Cutler completing a 3-yard and a 14-yard TD pass to TE Tony Scheffler. San Diego would immediately respond with RB Darren Sproles returning a kickoff 103 yard for a touchdown, yet the Broncos replied with kicker Matt Prater getting a 52-yard field goal. The Chargers would strike at Denver's lead as QB Philip Rivers completing a 48-yard TD pass to WR Chris Chambers, yet the Broncos would end the half with Cutler completing a 6-yard TD pass to WR Brandon Marshall. In the third quarter, the 'Bolts began to rally as Rivers completed a 15-yard TD pass to Chambers, along with Kaeding nailing a 21-yard field goal. In the fourth quarter, San Diego took the lead with Kaeding's 28-yard field goal and Rivers' 66-yard TD pass to Sproles. However, Denver responded with a 12-play, 80-yard drive (which included a second controversial officiating call that turned a game-winning fumble into an incomplete pass) that concluded with Cutler completing a 4-yard TD pass to WR Eddie Royal, including Cutler's 2-point conversion pass to Royal. Notable: The game has been titled by press and websites as "The Mile High Highjacking" after the officiating call that cost San Diego the game.

Input: John, the eldest son of King Manuel I to his second wife Maria of Aragon, was born in Lisbon on 7 June 1502. The event was marked by the presentation of Gil Vicente's Visitation Play or the Monologue of the Cowherd in the queen's chamber. The young prince was sworn heir to the throne in 1503, the year his youngest sister, Isabella of Portugal, Empress Consort of the Holy Roman Empire between 1527 and 1538, was born. John was educated by notable scholars of the time, including the astrologer Tomas de Torres, Diogo de Ortiz, Bishop of Viseu, and Luis Teixeira Lobo, one of the first Portuguese Renaissance humanists, rector of the University of Siena and Professor of Law at Ferrara . John's chronicler Antonio de Castilho said that, "Dom Joao III faced problems easily, complementing his lack of culture with a practice formation that he always showed during his reign" . In 1514, he was given his own house, and a few years later began to help his father in administrative duties. At the age of sixteen, John was chosen to marry his first cousin, the 20-year-old Eleanor of Austria, eldest daughter of Philip the Handsome of Austria-Burgundy and Queen Joanna of Castile, but instead she married his widowed father Manuel. John took deep offence at this: his chroniclers say he became melancholic and was never quite the same. Some historians also claim this was one of the main reasons that John later became fervently religious, giving him name the Pious .
