Kevin Durant is expected to miss Game 4 of the Western Conference quarterfinals after further testing revealed a bone bruise in his sprained left ankle, sources told ESPN on Sunday. The Houston Rockets star sustained the injury during Game 2 against the Los Angeles Lakers. His absence would be a significant blow to the Rockets' playoff hopes.

Durant, who averaged over 25 points per game this postseason, had been a key factor in the series. The Rockets currently trail the Lakers 2-1 in the best-of-seven matchup. Without their leading scorer, Houston will need to lean on James Harden and role players to keep the series alive.

The bone bruise diagnosis came after additional imaging on Sunday, according to the report. There remains no official timeline for Durant's return beyond Game 4. The Rockets have not yet commented on potential lineup changes in his absence.

Game 4 is scheduled for Tuesday at the Lakers' home arena. If the Rockets fall to a 3-1 deficit, Durant's status for Game 5 becomes even more critical. An extended absence could derail Houston's championship aspirations.

Some analysts note the injury may be a precautionary move, as playing through a bone bruise risks further damage. The Rockets' front office is reportedly taking a cautious approach.
