International Cricket Council chief executive Haroon Lorgat says a 'timeless' Test match could be played in 2013.
The inaugural World Test Championship is set to take place in England in two years' time and the ICC is considering options to ensure there is a result in the final of the competition.
Led by general manager Dave Richardson, the ICC are considering running the final Test until all four innings are complete, regardless of how long it takes.
Lorgat revealed the plan at a press conference at Lord's on Monday.
"We've still got to decide how we determine a winner in case of a draw or if the draw will be the end result. I would favour a winner because you want somebody to be a Test champion," he said.
"That is what Dave Richardson and the committee is currently working on because it is not a good idea to end up with a drawn Test match.
"You have got to determine a winner, whether it is on the first innings basis, or the runs in the game. They will come up with a viable formula to determine a winner in case of a drawn Test match.
"The final may well be a timeless Test. We don't know that yet but we are looking into the mechanics of that, although looking at the statistics today, most of the games have ended in results."
Lorgat said he was keen to have the discussion settled and a decision made 'before the end of the year'.
He said he was confident people were still interested in the longest form of the game, but the ICC needed to ensure matches were competitive.
"I'm confident that as we produce a context in a Championship for Test cricket and we get better contests, as we have seen in the last few series, you will get back the interest and then see what the World Test Championship can do for us," Lorgat said.
"People back winners when they see challenging matches."
Lorgat believes Test cricket's best nations - India, South Africa, England, Sri Lanka and Australia - are already vying to ensure they are in the top four to be able to compete at the World Test Championship.
