Absent the past two San Antonio Spurs games because of undisclosed medical reasons, head coach Gregg Popovich will re-join the Texas team when his Spurs visit the Boston Celtics on Sunday afternoon.

As with most of his interviews with reporters in the past, the exchange by the Spurs head coach between scribes pre-game in Boston were light-hearted and funny.

"Sure. I don't know what else I would do. It’s winter, you know, plants don't grow. I'm having a fight about books right now because I've decided that, at my age, there's so many things you want to read, that you can't do it,” Popovich shared when asked if he missed coaching via ESPN.COM. “So do you just give up and read nothing, or do you go into high gear and read everything that you can find? I just thought I'd throw that out there."

However, Popovich turned serious when asked to compare coaching his team from the sidelines and watching the Spurs on television.

“You realize that it's probably harder for the people that watch than the people that are in the battle. Your family, [general managers] and their staff -- you watch it and you don't have any control over anything. You just live and die with every play and every call, that sort of thing. So it's much easier sitting on the bench and being in the middle of the fight,” Popovich said in the same article.

The defending champions did not miss a beat without their lead mentor stretching their current winning streak to six games. In the past two outings, Ettore Messina, assistant coach of the Spurs, led them to victories over the Indiana Pacers, 106-100 and Sacramento Kings, 112-104 at home.

The Spurs, which has 11 wins in 15 games so far this season, take on the Celtics on Sunday afternoon and face the Philadelphia 76ers on Monday before wrapping up their three-game East road trip agains the Brooklyn Nets on Wednesday. The Celtics have lost six of their last seven games and are on a a three-game skid while the Sixers are winless in 16 games so far this season— Popovich’s return might not even be needed as the Spurs are looking at a couple of easy games in their schedule.
