Terry, who was found not guilty earlier this summer of racially abusing Anton Ferdinand, is currently part of an FA investigation into the same situation.
A source said: "Fabio Capello and Franco Baldini were approached a few weeks ago to provide witness statements. Fabio asked the FA, and they had no objection.
"John Terry's lawyers asked a few questions, and Fabio and Franco gave their answers in a statement. The questions were not concerning the facts of the case as Franco was no longer working for the FA when it happened and Fabio was not there and so didn't know what happened that day.
"They were about the general policy of the FA in similar circumstances, about the FA's attitude toward court proceedings and how that impacted on their own disciplinary procedures.
"Fabio had a couple of players either involved in a fight in a pub or car crashes, but they were not sport related. The John Terry case happened on the pitch, and was therefore related to football."
The disciplinary hearing continues tomorrow at Wembley.
