On 8 September 2007 Widdrington was involved in a touchline incident with Rushden & Diamonds boss Garry Hill. The pair began arguing and Hill headbutted Widdrington, breaking his nose. Both men received fines from their clubs and Hill was also given a ten match touchline ban and a fine of £1,500. Later that year Widdrington was suspended by the club pending an 'internal disciplinary inquiry', but was soon allowed to return to work, with a statement being released saying: "No charges have been brought against Tommy and everyone at the club looks forward to working with him towards continued success." The following year Rushden banned him from Nene Park in the return fixture, despite no authorisation from The Football Association for the action.
