<human>: Background: Benjamin Todd Roethlisberger Sr. (; born March 2, 1982), nicknamed Big Ben, is an American football quarterback for the Pittsburgh Steelers of the National Football League (NFL). He played college football at Miami University (Ohio), and was drafted by the Steelers in the first round (11th overall) of the 2004 NFL Draft. Roethlisberger earned the AP NFL Offensive Rookie of the Year Award in 2004 and his first Pro Bowl selection in 2007.
Context: On March 13, Roethlisberger signed a five-year contract extension with the Steelers. Roethlisberger went 26 for 38 for 351 yards, one touchdown pass and one interception during a 28-21 loss against the Patriots to kick off the 2015 NFL season. However, Roethlisberger and the Steelers would bounce back to win their next two games against the San Francisco 49ers and the St. Louis Rams. In the 43-18 victory over the 49ers, he had 369 passing yards and three touchdowns to earn AFC Offensive Player of the Week.  During the September 27 game against the St. Louis Rams, Roethlisberger suffered a sprained MCL and a bone bruise. Roethlisberger missed the Steelers' next four games, during which Michael Vick and Landry Jones combined to go 2-2.  Roethlisberger sustained another injury against the Oakland Raiders on November 8, 2015, suffering a left mid-foot sprain. Due to this injury, he did not start the following week against the Cleveland Browns, although he was listed as active for the game. However, early in the first quarter, Landry Jones sprained his left ankle, resulting in Roethlisberger entering the game in relief for only the second time in his career. Roethlisberger threw for 379 yards and 3 touchdowns on the way to a Steelers win and an AFC Offensive Player of the Week award; his 379 passing yards were the most by a quarterback in relief since Don Strock threw for 403 yards in the Epic in Miami. On November 29, Roethlisberger threw for 456 yards against the Seattle Seahawks, but he also threw 2 interceptions, and the Seahawks took a 39-30 win.  The Steelers clinched a playoff spot with a 10-6 record, finishing second in the AFC North behind the Cincinnati Bengals. They then defeated the Bengals by a score of 18-16 in the Wild Card round, but lost to the eventual Super Bowl champion Denver Broncos in the Divisional round by a score of 23-16. Roethlisberger was named to his fourth career Pro Bowl and was ranked 21st by his fellow players on the NFL Top 100 Players of 2016. CANNOTANSWER
