NFL legend Steve Smith Sr visited Meadow Lane as part of the NFL's UK Roadshow.
The wide receiver, who spent 13 years with the Carolina Panthers and two with the Baltimore Ravens before retiring in January, joined Notts striker Shola Ameobi to discuss their respective sports before taking penalties against young goalkeeper Joe Searson-Smithard.
Manager Kevin Nolan also got involved, teaching Smith Sr volleys - and even the famous chicken dance celebration!
