The Daily Mail says Richards was handed a start against Bayern Munich in the Allianz Arena on Tuesday night but his evening was cut short when was forced off with a hamstring problem after just sixteen minutes, with City trailing 2-0.
The defender looked devastated by his latest injury blow, although his spirits will have been raised by City's magnificent comeback, as his team recovered to win 3-2 in Munich.
After the match, Richards tweeted: 'Am sorry City fans.'
His apologetic message was greeted with dozens of supportive messages, as City fans showed their appreciation for a homegrown player that has been with the club since the age of 14.
Thanks for the support! For this great support id like to offer 20k of my own money to anyone who convinces me there charity needs it most.
