Top Spurs assistant Ettore Messina will continue to serve as the club’s interim head coach for Game 5 of its series against the Warriors on Tuesday, the team announced today. It will be Messina’s third game as head coach this series. Messina is filling in for Gregg Popovich, who is away from the team mourning the death of his wife Erin. The Spurs will give Popovich as much time as needs, so it’s not clear if we’ll see him again on the sidelines this season. The Spurs currently trail the Warriors 3-1, with Messina having helped lead the team to a victory at home in Game 4.
