2019 Jacksonville Jaguars season
The 2019 season was the Jacksonville Jaguars' 25th in the National Football League and their third under head coach Doug Marrone.
The Jaguars signed quarterback Nick Foles to a four-year, $88 million contract on March 11, 2019. It was also their first season since 2013 without Blake Bortles on the roster, as Bortles signed with the defending NFC champion Los Angeles Rams in free agency on March 18, 2019. Foles suffered a clavicle injury in week 1, and was replaced with rookie Gardner Minshew for the majority of the season. The Jaguars slightly improved on their 5–11 record from the previous season, but were mathematically eliminated from playoff contention for the second consecutive season after a loss to the Los Angeles Chargers.
This season, the Jags became the first team since the 1986 Tampa Bay Buccaneers to lose five straight games by 17 points or more.
