Running back Beanie Wells became one of the rare players in NFL history to suffer a season-ending Achilles injury during a tryout last week.
While trying out for the Baltimore Ravens on Wednesday, the former first-round pick of the Arizona Cardinals hurt his Achilles and it prevented him from finishing the workout.
The injury is so bad, per league sources, that Wells will not be able to work out for any other teams in the coming weeks, ending his season before it began.
The Ravens ended up adding depth at running back by signing Bernard Scott on Monday. A sixth-round pick by the Cincinnati Bengals in 2009, Scott played the past four seasons for the Bengals before being released on Sept. 17.
Scott, 29, provides insurance in case backup Bernard Pierce can't play Sunday at the Cleveland Browns. Pierce injured his hamstring in the Ravens' last game in Pittsburgh and didn't participate in the last practice before the bye.
Wells, a former Ohio State standout, who battled injuries during his four seasons in Arizona, was released by the Cardinals in March.
Wells eclipsed 1,000 yards and scored 10 touchdowns in 2011, but he was limited to eight games last season by a turf toe injury. Last season, he ran for 234 yards and eight touchdowns as part of what was the worst offense in the NFL.
Coming off their Super Bowl season, the Cardinals selected Wells out of Ohio State with the 31st overall pick in 2009.
