How the Cincinnati Bengals beat Kansas City in the A.F.C. championship game to reach their first Super Bowl since the 1988 season.
San Francisco extended its lead against the Rams to 17-7 late in the third quarter after quarterback Jimmy Garoppolo found tight end George Kittle in the end zone.
The 49ers got the ball after their defense forced a Rams turnover on downs on the previous possession. On fourth-and-1, quarterback Matthew Stafford lunged over the pile at the line of scrimmage but was stopped in the air, short of where he needed to go down.
