A rash of major injuries struck the NFL during a series of rookie minicamps.
On Friday, the Jacksonville Jaguars lost first-round defensive end Dante Fowler to a season-ending torn anterior cruciate ligament during a pass-rushing drill.
On Saturday, Denver Broncos third-round tight end Jeff Heuerman tore his anterior cruciate ligament and is also out for the season.
The Ravens weren't immune to the injury bug as one of their top undrafted rookies was part of the trend.
Former Oklahoma cornerback Julian Wilson, who joined the Ravens on a $9,000 signing bonus after being sought by the Seattle Seahawks, Kansas City Chiefs, Atlanta Falcons and Cleveland Browns, suffered a broken leg Friday that required surgery. He is out for the season.
There's really no explanation for the injuries. These were non-contact drills. Sometimes, young players push themselves extremely hard during these initial NFL moments as they try to establish themselves and impress the coaches.
