Chelsea chairman Bruce Buck and England left-back Ashley Cole are attending the FA hearing, which relates to allegations Terry used racist language towards Anton Ferdinand during the QPR versus Chelsea match on October 23, 2011.
The centre-back was cleared of the racism charge in court earlier this summer, but, should he be found guilty by the FA in this week's hearing, Terry could face a lengthy ban.
On Sunday night, the Englishman announced his retirement from international football, after claiming the FA has made his position "untenable".
Wilkins told ESPN: "I called John immediately after his decision to resign from the England team to see how he is. We didn't talk about my attendance at the FA hearing, but I am there for him if he needs me.
"I gave evidence on his behalf at the magistrates' court and I would do so again at the FA hearing, if they wish me to."
