Kirk Hinrich ditched the walking boot he wore in New York to protect his severely bruised left calf. The pessimism surrounding his chances to play in Thursday's Game 6 remains. "I'd have to improve some definitely," Hinrich said. "I'm taking it day-to-day and trying to throw everything at it (treatment-wise) to try to improve it as quickly as possible." Hinrich didn't practice Wednesday and limped to a podium to address reporters. He said his swelling has decreased some but remains throughout his lower leg. "I'm still walking very gingerly," Hinrich said. "I haven't tried to run or cut or jump or anything yet. I'm hoping it improves a lot. ... It's just one of those things where I took a good shot and it's preventing me from moving very well." Hinrich, who suffered the injury taking a charge from Deron Williams, said sitting out is "brutal." Coach Tom Thibodeau wouldn't say who would start in the likely scenario of Hinrich sitting. Nate Robinson made his first career playoff start in Game 5 and finished with 20 points, eight assists and three turnovers but struggled to limit Williams' penetration. "Deron is a tough cover," Hinrich said. "He's one of the best there is in the league."
