Davis will be listed as day-to-day going forward, Shams Charania of The Athletic tweets.
Davis, who sustained the injury at the end of the first half, finished with six points, four rebounds and three assists. The Lakers played without Kentavious Caldwell-Pope due to a knee contusion, and LeBron James also admitted this week that he needs around-the-clock treatment to keep his ankle ready.
Davis was dealing with a left knee sprain coming into the contest. He averaged 27 points and 9.3 rebounds per game (39.7 MPG) in the team’s first three games of the series, shooting 43% from the floor.
The Suns will host the Lakers in Game 5 on Tuesday after tying the series 2-2. Davis’ status is naturally uncertain.
