Serge Ibaka listed as day to day

— -- OKLAHOMA CITY --  Thunder power forward Serge Ibaka, who was expected to miss the rest of the postseason after suffering a left calf injury in the Western Conference semifinals, is participating in light drills and is listed as day to day, the team announced Friday.

"At present, Serge has yet to complete a full basketball workout but is walking and doing light basketball drills," Thunder general manager Sam Presti said in a statement. "With this new information, and in an effort to keep his status current, we are now listing him as day to day with the understanding that there is a possibility for him to play in this series."

The Thunder trail the San Antonio Spurs 2-0 in the conference finals, having lost the first two games by a combined 52 points. The best-of-seven series shifts to Oklahoma City for Games 3 and 4 on Sunday and Tuesday.

The 6-foot-10 Ibaka suffered a Grade 2 strain of the plantaris in the Thunder's series-deciding victory against the Los Angeles Clippers on May 15. Team officials originally said the injury takes a long time to heal and strengthen because of a high reinjury rate.

"The abundance of blood and therefore swelling in Serge's calf has reduced substantially and unexpectedly, allowing a level of movement and stability not thought possible after the initial diagnosis," Presti said in the statement. "Based on both imaging and physical exam, the considerable swelling in the calf indicated the likelihood of a certain degree of injury, and that established the original time frame for recovery."

Ibaka has averaged 12.2 points, 7.3 rebounds and 2.2 blocks in 13 playoff games. During the regular season, he notched career highs with 15.1 points and 8.8 rebounds per game while leading the league in blocks (219) for the fourth consecutive season.
