(Reuters) - The Pittsburgh Steelers clinched their first playoff berth in three seasons when they defeated the Kansas City Chiefs 20-12 on Sunday.
The six-time Super Bowl champions had not qualified for the postseason since losing a wild-card game to the Denver Broncos following the 2011 regular season.
Steelers quarterback Ben Roethlisberger directed the Steelers (10-5) to their third consecutive win, passing for 220 yards and a touchdown.
Roethlisberger suffered a right knee injury in the third quarter while throwing the deciding touchdown pass to wide receiver Antonio Brown but returned after receiving treatment and did not miss any playing time.
