Could he be sent down again if found guilty again?

No, he either gets to clear his name or his conviction stands but the charge against him is still the same.  McDonald, the other player involved, is not part of this trial and cannot be tried again for it anyway having been found innocent.

The rule of "double jeopardy" was recently changed (in 2003) so that a person could be tried twice for the same offence for certain serious crimes (including murder, manslaughter, kidnapping, rape, armed robbery, and serious drug crimes) provided there is "fresh and viable" new evidence and the DPP approves and quashes the original acquittal.
