In October of 2008, Marlin Jackson suffered a season-ending knee injury. In June of 2009, he again suffered a season ending knee injury.
And now today, there's this two sentence release from the Eagles:
After an MRI this afternoon, Eagles defensive back Marlin Jackson was diagnosed with a ruptured Achilles tendon in his right leg. He suffered the injury during the Organized Team Activities this afternoon.
Jackson was "visibly upset" after injuring his ankle causing many to fear the worst. It's safe to say a ruptured Achilles falls under the "worst" category.
At some point, you've gotta be wondering when one of these injuries will be career-ending.
