Tim Duncan's decision to sign a two-year contract extension that will take him through the 2011-12 season has left Gregg Popovich no choice: his planned retirement will have to wait at least that long.

Popovich often has joked that as soon as Duncan retires, he is leaving the Spurs' bench, as well. Popovich will be 62 before he can relax full-time at his winery in Oregon or his summer home in Maine.

"He screwed me over," the 58-year-old Popovich said before the Spurs opened the regular season against the Portland Trail Blazers at the AT&T Center, when asked if he will have to wait to retire until Duncan is done playing.

"I'm going to be forced into it now. I already had plane reservations. I had all kinds of stuff where I was going, and he screwed me."
