Smith is close to scoring 10,000 runs in the longest format of the game.
Smith, who boasts an impressive average of 58.61 in Test cricket, has failed to live up to his high standards lately. The 102-Test veteran has averaged 34 since the end of the previous home season, which included trips to India and England.
"I can debunk that at this point in time," Craig told the Sydney Morning Herald. "He's still talking about things he wants to achieve."
Smith is on the cusp of scoring 10,000 runs in the longest format of the game. He has 9320 Test runs to his name so far, including 32 hundreds and 39 half-centuries.
Earlier this year, Steve Smith dismissed the retirement rumours after former England skipper Michael Vaughan claimed to have heard unattributed "whispers" within cricket circles that the Aussie legend was about to put up his gloves.
"I'm not retiring. I have no idea (where it's come from), because I haven't said it to anyone. I am not going anywhere yet," Smith had said.
Steve Smith will be next seen in action in the upcoming Test series against Pakistan at home, starting on December 14 in Perth
