Raiders starting right tackle Menelik Watson suffered a serious injury in Sunday night’s preseason game.
Watson tweeted after the game that he has ruptured his Achilles tendon. That is almost always a season-ending injury.
The Raiders’ second-round pick in 2013, Watson was a project when he was drafted: He grew up in England and had played only two seasons of football in his life. But he started nine games last year and all three preseason games and was projected to be the Week One starter at right tackle this year. Instead he’ll spend the year rehabbing.
