Across the country, Premier League players wore the shirt designed by the anti-racism campaigners but the United defender decided against showing his support following the handling of the incident involving his brother Anton and John Terry a year ago.
Ferguson told BBC Sport: "At the press conference yesterday I spoke to the press about it.
"It is embarrassing for me. He will be dealt with, no doubt about that."
Joleon Lescott and Jason Roberts also decided against wearing the T-shirts before their games for Manchester City and Reading, respectively.
