Anthony Davis provided a positive assessment over the ankle injury he suffered in Game 4 of the Western Conference finals, declaring: "I'll be fine."

Davis rolled his ankle in the fourth quarter of the Los Angeles Lakers' 114-108 triumph over the Denver Nuggets on Thursday, putting them 3-1 up in the best-of-seven series and on the brink of a place in the NBA Finals.

Despite the setback, the 27-year-old still led the Lakers in terms of scoring, contributing 34 points as he played 41 minutes.

Game 5 takes place on Saturday, with Davis confident of being fit for action as Los Angeles aim to close out the Nuggets and progress to the NBA Finals.

"Ankle feels fine," the seven-time All-Star told the media. "Got tonight, tomorrow before the game to get it back to, I don't want to say back to where it was, but good enough to play.

"Rolled it pretty bad but not too bad. I'll be fine."

While the Lakers are clearly firmly in control, they will be wary of allowing the Nuggets to climb off the canvas following their heroics in the previous two rounds.

Denver battled back from 3-1 deficits to see off the Utah Jazz and the Los Angeles Clippers, leading Davis to speak out about the dangers of taking anything for granted.

"You know, like I said last game, we've got to put them away," he said. 

"They are going to continue to fight, no matter what the score is, no matter what the situation is, we just have to make sure we counter everything they do."

The Lakers have not reached the NBA Finals since 2010, which was also the last time they were crowned champions.
