Cecil Shorts has been ruled out for several weeks after pulling his hamstring during the Jacksonville Jaguars' training camp.
The wide receiver has already missed time in the off-season after picking up a calf injury.
The 26-year-old told the team's official website: "I can't catch a break right now, but it's all good I guess. My frustration level might be up at an all-time high, honestly."
Shorts had 777 receiving yards and three touchdowns during the 2013 season.
