Looking resplendent in a suit and tie, Boris Diaw blended in with the beautiful people courtside at Staples Center during the final two games of the Spurs’ first-round playoff sweep of the Los Angeles Lakers. The 31-year-old reserve forward hopes to slip into something a little more utilitarian by the time the Spurs start the second round. Out of action since April 12 surgery to remove an olive-sized cyst from the base of his spine, Diaw says he’s “getting close” to returning to the Spurs’ active roster. He could suit up for Game 1 of the Western Conference semifinals against either Golden State or Denver, a series that would not begin until Monday. “I’m feeling good,” said Diaw, who on Tuesday came out of a second full-contact practice with no trouble. “It shouldn’t be much longer.” Diaw last played April 6 against Atlanta, exiting the game in the first half after noticing a problem with his right leg. Namely, that it wasn’t functioning. “You go to move your leg, and you can’t move it,” Diaw said. “That’s a problem.” Team doctors initially feared a disc issue in Diaw’s lower back, which if serious enough might have cost him the remainder of the season. It was a relief to Diaw — albeit a painful one — when an MRI revealed a synovial cyst in his lumbar spine. The mass was pressing against his sciatic nerve, which controls the sensory and motor function in the leg. Immediate surgery to remove it was mandatory. If left alone, Diaw says, he could have eventually lost function in his leg. “If you let it go, it could mean permanent nerve damage,” Diaw said. “That’s not just basketball. That’s life.” Diaw’s post-surgery prognosis is positive, although the procedure caused him to miss the final five games of the regular season plus the first four of the playoffs. After making it through two full, fruitful practices without incident — and with more to come before the Spurs take the floor again — Diaw is poised to be a contributor in the next round. “He did the whole practice and seems to have come out of it pretty good,” coach Gregg Popovich said Tuesday. “I would think he’ll be available.”
