The Magpies have launched an investigation into an incident after the Under-21 team's 2-0 defeat at Sunderland on Monday evening.
It is understood the 62-year-old former Scotland international's conduct is being probed after it was claimed he was involved in an altercation with 19-year-old defender Remie Streete.
Mind you, being struck by a 62-year-old pensioner can hardly do Remie's 'street cred' much good!
