the Colts to an overtime win, defeating the Jacksonville Jaguars, 16–13. After a short week that included Hasselbeck being ill from a bacterial infection and having virtually no practice time, he was once again called upon to play for Luck. He became only the second 40-year-old NFL quarterback to win back-to-back games, when he engineered a 27–20 win over the Houston Texans on October 8, 2015. Over those two starts, he completed 48 of 76 passes for three touchdowns and no turnovers, compiling a 2-0 record as starter. On November 22, 2015, Hasselbeck started his third game for the Colts, as Luck suffered a kidney injury that would ultimately take him out for the remainder of the season. He passed for 213 yards with two touchdowns and two interceptions in a come-from-behind win over the Atlanta Falcons. The win kept Indianapolis in the lead of the AFC South division and improved them to a 5–5 record. The following week, the Colts took on the Tampa Bay Buccaneers, who were on a four-game winning streak. Hasselbeck led the team to a 25–12 win, passing for 315 yards with two touchdowns and no interceptions, which led to a passer rating of 100.8. Hasselbeck led the Colts to a 6-5 record with a 4-0 record as starter at the age of 40, and was the first quarterback in NFL history to do so. However, injuries began to take their toll on the aging quarterback, and Hasselbeck's play would begin to deteriorate as the Colts lost three straight games. Hasselbeck won the final start of his career, an 18-12 win over the Miami Dolphins, thanks in large part to Frank Gore's two rushing touchdowns. He and backup Charlie Whitehurst were unable to play the season finale due to injury; to take their place the Colts signed Josh Freeman and Ryan Lindley, who subsequently split time in a 30-24 win over the Titans. Overall, Hasselbeck was responsible for five of the Colts' eight wins over the season, despite only starting eight games. Retirement On February 28, 2016, it was reported that Hasselbeck would not return to the Colts. On March 9, 2016, Hasselbeck announced his retirement from professional football, and that he would join his brother Tim and become an analyst for ESPN, replacing Mike Ditka on Sunday NFL Countdown. Hasselbeck signed a one-day contract with the Seattle Seahawks to officially retire as part of
