Buffalo Bills rookie linebacker Kiko Alonso's second interception of the game with 57 seconds remaining sealed a 23-20 win over the Baltimore Ravens on Sunday.
Converted safety Aaron Williams also intercepted Joe Flacco twice, while Fred Jackson had 87 yards rushing and a touchdown for Buffalo (2-2).
Robert Woods scored on a 42-yard touchdown reception. Buffalo totaled 213 yards rushing against a stout Ravens defense that had allowed just 224 in its first three games.
Joe Flacco threw a career-worst five interceptions, and finished 25 of 50 for 347 yards passing, and two touchdowns.
Torrey Smith had five catches for 155 yards and a 26-yard touchdown for the Ravens (2-2).
The Ravens' last chance to tie the game ended when Flacco forced a pass over the middle intended for Dallas Clark. Safety Da'Norris Searcy got a piece of the ball, which bounced into the air and was intercepted by Alonso.
