Pittsburgh Penguins captain Sidney Crosby is suffering from post-concussion syndrome after an incident at practice last Friday. Wednesday morning, in his second straight day of skating, Crosby participated in some non-contact drills with Bryan Rust ahead of the Penguins’ full practice.

Later, Penguins’ Head Coach Mike Sullivan ruled Crosby out for the Penguins’ season opener and Stanley Cup banner raising against the Washington Capitals.

Sullivan: "(Crosby) is obviously feeling well enough that he wants to join the team for practice and get involved in some flow drills." -MC — Pens Inside Scoop (@PensInsideScoop) October 12, 2016

Sullivan on Crosby: "We'll take each day as it comes. We’re encouraged by the progress he's made to this point and we’ll go from there" -MC — Pens Inside Scoop (@PensInsideScoop) October 12, 2016

The news bummed out Caps Head Coach Barry Trotz.

“Actually, I wish he was playing,” Trotz said after practice to CSN Mid-Atlantic’s Tarik El-Bashir. “I do. Going into Pittsburgh, you want to see their best, right from the start.”

“I got to spend some time with Sid at the World Cup of Hockey,” Trotz continued. “He’s a good person. He’s a terrific player. He’s all those things. It’s unfortunate. He’s had a lot of them. You see a top player have a lot of concussions, that’s not good for any athlete. Just wish him well.”

Crosby has missed parts of two seasons due to head injuries earlier in his career.

Get well soon, Sid.
