HOUSTON (AP) — From the couch to the playoffs, Joe Flacco had an incredible run with the Cleveland Browns. But his stretch of success came to a sudden end on Saturday, when the Browns lost 45-14 to the Houston Texans in a wild-card playoff matchup. Flacco had interceptions returned for touchdowns on consecutive drives in the third quarter to turn a close game into a laugher. It was Cleveland’s worst playoff loss since a 34-0 defeat to the Baltimore Colts on Dec. 29, 1968. The 39-year-old Flacco went 4-1 as a starter in the regular season to carry the Browns to the playoffs after Deshaun Watson suffered a season-ending shoulder injury.
