A season filled with hope and promise in Kansas City is about to go down the drain. One day after being crushed by a mediocre team in their home opener, the Chiefs have received devastating injury news. Young safety Eric Berry, who is by all indications a superstar in the making, will miss the rest of the season with a torn ACL, according to NFL Network’s Jason La Canfora.

As a 21-year-old rookie in 2010, the No. 5 overall pick out of Tennessee immediately emerged as one of the league’s top safeties. Kansas City’s inability to force turnovers hurt them down the stretch in 2010, and Berry, with a year under his belt, was supposed to help solve that issue in-house in 2011.

He had two sacks, four picks and a touchdown while playing every snap in 2010, earning a spot in the Pro Bowl.

This is the biggest blow imaginable for a young Chiefs team, but it’s not the first major injury the team has had to deal with in 2011. Quarterback Matt Cassel is fighting a rib injury and young tight end Tony Moeaki, who was Cassel’s second-favorite target last year, was lost for the season last weekend.

Now without two of their brightest young stars, the Chiefs have to go on the road to play Detroit and San Diego the next two weeks. It’s very likely they drop to 0-3 and out of the AFC West race early. Considering that, dating back to Week 17 of last season, they’ve lost their last three games by a combined score of 102-24, there isn’t a lot of hope for KC right now.
