A Nike shoe designer mocked Derrick Rose's season-ending ACL injury on Twitter on Sunday, igniting a firestorm of criticism on the social media website.

Jason Petrie, who designed LeBron James' signature sneakers, tweeted that Rose should have signed with Nike after the Chicago Bulls superstar tore his ACL in the final minutes of Game 1 of Chicago's Eastern Conference quarterfinals series against the Philadelphia 76ers.

"You got one guy only getting stronger, and one guy breaking down before our very eyes. You chose poorly Pooh... #shouldasignedwithNIKE #GWS," Petrie wrote, referring also to James and Heat's 33-point Game 1 victory over the New York Knicks.

Rose signed long-term deal with rival shoemaker adidas in February.

Petrie's comments drew enough outrage that Petrie tried to assuage his followers, tweeting: "Y'all take sh#t too serious! Never want to see anyone get hurt- I hope DRose comes back stronger than ever, he's too good..."

FoxSports.com reported Sunday that Petrie then went back on the offensive Saturday, writing, "Just to set the record straight- if you ain't with me you against me, and if that's the case I don't give a F about you!"

On Sunday morning, Petrie apologized for his comments.

"Wow! Twitterverse I do apologize. It was really just tongue n cheek! Never meant any harm or disrespect!," he tweeted.
