Here is the statement from Pace:
This was a mild surprise because Pace is both a smart player and a smart guy. We don't know yet where he got whatever it is he took, although it was clearly stated that it was something over the counter. I just got off the phone with another player on the team who theorized that Pace most likely took something on the recommendation of someone he trusted and just didn't check every single ingredient in whatever it was he took.
As soon as I find out more, I'll let you know.
Right now, third-year veteran Marques Murrell is listed as being behind Pace on the depth chart, but this is also an opportunity for Vernon Gholston to step up.
