The Flyers, who resume their season Aug. 2 against Boston, released their 34-player training-camp roster Monday, and it was composed of 18 forwards, 12 defensemen and four goalies.

Center Nolan Patrick, who has missed the entire season because of a migraine disorder, was not on the roster.

General manager Chuck Fletcher said he and trainer Jim McCrossin have been in constant contact with Patrick and that “frankly, our focus is on getting him ready for the 2020-21 season. We really want to be prudent in this matter and prioritize his health and safety over the long run.”

Patrick, who scored 13 goals in each of his first two seasons, is “going to be a big part of our future,” Fletcher said.

Fletcher said Patrick, the No. 2 overall selection in the 2017 draft, told him that “lately, this is the best he’s felt in the last 12 months. He feels he’s making progress. Sleeping better. He’s able to exercise, able to skate.”

The roster includes 11 players who spent most of the season with the AHL’s Phantoms; they are in camp in case of injuries or illnesses to those expected to be in the lineup.

Perhaps the biggest surprise: The roster includes defenseman Egor Zamula, 20, who played just 28 games with the Western Hockey League’s Calgary Hitmen last season and then required back surgery. He had seven goals, 28 points and a plus-19 rating.

The Inquirer lists the 6-foot-4 Zamula, signed by then-GM Ron Hextall as an undrafted free agent in 2018, as the organization’s third-best prospect, behind center Morgan Frost and defenseman Cam York.

“We’re certainly cognizant that he’s coming off a tough surgery, and he’s 20 years old,” Fletcher said of Zamula. “We thought it would be good for him, long-term, to come back and participate and skate with our group — and over the next two weeks, the coaches will have to make that decision as to whether he’d be a factor for Phase 4″ when the games are played. “But make no mistake about it, this kid is a top prospect and he’s going to have a very good career for us.”

Teams are allowed to have 30 skaters and an unlimited amount of goalies at camp.

Here is the roster:

FORWARDS (18): 10 Andy Andreoff, 11 Travis Konecny, 12 Michael Raffl, 13 Kevin Hayes, 14 Sean Couturier, 18 Tyler Pitlick, 21 Scott Laughton, 25 James van Riemsdyk, 28 Claude Giroux, 38 Derek Grant, 44 Nate Thompson, 48 Morgan Frost, 49 Joel Farabee, 50 German Rubtsov, 62 Nic Aube-Kubel, 81 Carsen Twarynski, 82 Connor Bunnaman, 93 Jake Voracek.

DEFENSEMEN (12): 3 Andy Welinski, 5 Phil Myers, 6 Travis Sanheim, 8 Robert Hagg, 9 Ivan Provorov, 15 Matt Niskanen, 26 Tyler Wotherspoon, 39 Nate Prosser, 53 Shayne Gostisbehere, 54 Egor Zamula, 59 Mark Friedman, 61 Justin Braun.

GOALIES (4): 34 Alex Lyon, 37 Brian Elliott, 67 Kirill Ustimenko, 79 Carter Hart.

Surgery for Ghost

Gostisbehere, who is expected to be a spare defender in the postseason, revealed he had another operation about seven weeks ago, saying he had arthroscopic surgery on his right knee. “A small little cartilage thing,” he said.

The 27-year-old defenseman had arthroscopic surgery on his other knee Jan. 14.

The player they call Ghost said he is hopeful of being ready when the season resumes in Toronto.

Friedman signs

Mark Friedman, regarded as the Flyers’ No. 8 defenseman (if Gostisbehere is healthy) on the current roster, signed a one-way, two-year contract extension Monday with an annual salary-cap hit of $725,000, Fletcher announced.

Friedman, 24, played in six regular-season games for the Flyers this season. In 45 games with the Phantoms, he had three goals and 18 points.

He was selected in the third round of the 2014 draft at the Wells Fargo Center. The Flyers took Travis Sanheim and Nic Aube-Kubel with their first two picks, respectively. They selected Oskar Lindblom in the fifth round that year.
