Matty Fryatt accepts apology from Doncaster skipper
Fryatt faces several weeks on the sidelines after suffering the injury in a collision with Stock when the two clubs battled out a goalless draw at the Walkers Stadium on February 9.
"There is no way I would go out to hurt a fellow professional," said Stock, writing in the matchday programme ahead of the return on Tuesday night which City won 1-0.
"It was a total accident and the first time that I have done something like this to another player. To see him in such a bad way was unpleasant.
"As soon as it happened, my only function was to make sure that he was all right.
"To injure a player isn't me and it isn't my style. I have been in touch with Matty and he's accepted my apology.
"I wish him all the best for a very speedy and full recovery."
No action was taken against Stock for the challenge and City did not take the matter any further, although manager Nigel Pearson was clearly unhappy after reviewing video footage.
Stock missed Tuesday's clash at the Keepmoat Stadium with a back injury.
