There's no word yet as to when San Antonio Spurs head coach Gregg Popovich will return to courtside. Popovich has missed the team's last three games because of an undisclosed illness. On Thursday, prior to the game against the Portland Trailblazers, assistant coach Mitch Johnson said the 75-year-old is "doing good," but didn't know when he would be back in action. While Popovich is out, Johnson is taking on head coaching duties.
