Woods was spotted alongside golf instructor Matt Killen on the putting green ahead of this week's Players Championship.
The pair were captured on television cameras with Woods going through putting drills and Killen analysing the 14-time major winner's putting stroke closely.
Killen is best known as the short game coach of Justin Thomas and has also worked with other Americans JB Holmes, Kenny Perry, Nick Watney and Bud Cauley.
Woods is expected to give a press conference tomorrow at TPC Sawgrass which could not only shed light on his working relationship with Killen but confirm whether he will play this week having withdrawn from last week's Arnold Palmer Invitational citing a neck injury.
The 80-time PGA Tour winner hasn't worked with a coach since his split with Chris Como in December 2017.
