Serge Ibaka has made significant progress in his return from his calf injury and has been upgraded to day-to-day.

The Oklahoma City Thunder had previously ruled out Ibaka for the remainder of the postseason.

The San Antonio Spurs have raced out to a 2-0 lead in the Western Conference Finals with the absence of Ibaka being dully felt.

Ibaka is one of the best defensive big men in the NBA and his ability to stretch the floor has also limited the Thunder on offense without him.
