PFT Editor Mike Florio has checked in to report that he's hearing from sources with knowledge of the investigation that cornerback DeAngelo Hall could be the Falcons player called to testify if quarterback Michael Vick goes on trial. We previously noted that CBS 46 in Atlanta is reporting that an unnamed teammate of Vick's, described as "a prominent member of the team," could testify if Vick chooses to face a trial rather than plead guilty. Vick and Hall grew up in the same area of Virginia, and both attended Virginia Tech. Vick is three years older than Hall, and Hall has described Vick as a role model.
