The Sixers kick off their 2019 NBA playoff run Saturday afternoon with a Game 1 matchup against the red-hot Brooklyn Nets, but all the attention is focused on the health of superstar Joel Embiid.

On Friday, Embiid said the pain in his left knee had gotten so bad, he wasn’t sure if he would be available to play in Game 1 of the series. Embiid missed 14 of the Sixers’ final 24 games, and is officially listed as doubtful for Saturday.

“It really worries me, maybe because I had injuries,” TNT analyst and former Sixers forward Chris Webber said. “The playoffs are so long, it’s a grind and a haul. You’re going to need everybody at full strength, especial in the [Eastern Conference]. And so Embiid’s impending health issues … that’s what would worry me as a Sixers fan.”

On a positive note, Sixers fans in and around Philadelphia will have their choice of two broadcasts for the game, which is scheduled to tip off at the Wells Fargo Center at 2:30 p.m. Game 1 will air nationally on ESPN, with Dave Pasch on play-by-play alongside analyst Doris Burke. Here in Philadelphia, the game will also air on NBC Sports Philadelphia, with Marc Zumoff and Alaa Abdelnaby in the booth.

For the 2018-19 season, the Sixers averaged a 2.7 household rating on NBC Sports Philadelphia and NBC Sports Philadelphia+, up 12 percent compared to the 2017-18 season (which was up 45 percent compared to the 2016-17 season).
