Bills WLB Kiko Alonso tore his ACL while working out and is expected to miss the season.
It's a massive loss for a Bills defense that quietly ranked 10th in the league last year and was trending up. The versatile and athletic Alonso played every single snap during his standout rookie campaign, dominating in coverage and coming second in Defensive Rookie of the Year voting. He's been slapped with a 7-9 month recovery timetable and will likely be placed on injured reserve shortly. Next up at weak-side linebacker as the Bills shift to a 4-3 would be Nigel Bradham or Preston Brown.
