The Latics announced on their official website on Friday morning that Croft had left Boundary Park, with manager Lee Johnson stating that he had offered the winger a new deal but the deadline to accept it had now passed.
However, Croft has taken to Twitter to say this is not the case.
The 27-year-old tweeted: "Bit confused ova the article in the paper this morning. Iv had a great year @ the club n dont...
"Want things 2 end on this note. 4 the record, i did not turn down a contract, ther was no contract put infront of me or any negotiations.

"If there was issues with the deadline set, then that is between the club n my agent, i had no dealings with..The club since i met with the manager afew weeks ago."
Croft added: "Iv thoroughly enjoyed my year @ oldham n thank the fans 4 all there support thru out N as i said dont want things 2 end on this note as im sure the article this morning would have raised afew eye brows.
"I would like 2end with wishing the club n the gaffa all the best 4 nxt season, im sure it will b a successful one, thanks again 2 everyone x"
Croft joined Oldham last summer on a season-long loan from Derby but the move became a permanent transfer in January when his deal with the Rams was terminated. He featured in 53 of the Latics' 54 matches this season, more than any other player at the club.
