Atlanta had previously been linked with a move for Scotland-based striker Furuhashi and on Wednesday MLS posted an article on its website saying the Japan international had completed a transfer.
However, the MLS side, who had teased a new Japanese signing earlier in the week, announced it was former Japan under-23 forward Togashi who had arrived on a free transfer through the 2025 campaign.
"Major League Soccer's website mistakenly posted an article that named the wrong player as having signed with an MLS club," MLS said in a statement to ESPN.
"The article was immediately removed and corrected. MLS extends its sincere apologies to the impacted parties."
MLS did not immediately respond to a request for comment.
