Pop to Sager: 'I promise I'll be nice'

Spurs coach Gregg Popovich says he looks forward to sideline reporter Craig Sager's return and "I promise I'll be nice."

TNT's Sager is missing the NBA playoffs as he undergoes treatment for leukemia. So his son, Craig Sager Jr., filled in for Sunday's broadcast of San Antonio's playoff opener against Dallas, asking Popovich a few questions after the third quarter.

Popovich is famous for his terse answers to in-game questions from Sager and other sideline reporters. Sager even joked about it in a statement Friday confirming his diagnosis: "Too bad, I had some probing questions for Pop."
