Vincent Jackson and Antonio Cromartie tangled on a deep incompletion, and Jackson stayed on the ground midway through this afternoon's practice. Jackson got up a short while later, holding his hand. He rose and walked immediately to the training room. He has not come back on the field. Early word is the injury is not seriousVincent Jackson Injured During Practice I heard this on The Drive on 1360 and Kevin Acee confirms what they said on his blog. On the radio they said that he had a splint on, but I think they said it was just on his pinky finger.
