The 6-6, 270-pound Allen joins the Bears after spending four years with the Kansas City Chiefs (2004-07) and the previous six seasons (2008-13) with the Minnesota Vikings.
In 2013, Allen recorded his seventh consecutive double-digit sack season and eighth overall of his 10-year career. He started all 16 games for the 6th consecutive season, compiling 11.5 sacks, 13 TFLs, 52 tackles (33 solo), six pass deflections and two forced fumbles for Minnesota.
Allen leads the NFL in sacks with 128.5 since entering the league as a 4th round draft pick (126th overall) by the Kansas City Chiefs in 2004. In 157 career games, Allen has started 151, totaling 558 tackles (445 solo), five interceptions – including one returned for a touchdown – 51 batted passes, 29 forced fumbles, 17 fumble recoveries and is tied for a NFL record four safeties. In 2009, he joined Reggie White as the only NFL players to notch at least 14.5 sacks in 3 straight seasons (2007-09).
Allen broke the Vikings single-season sack record with 22 in 2011 and came within ½ sack of matching the NFL’s single season record. It was the second time Allen has led the league in sacks, a feat he first accomplished in 2007 with 15.5.
