Shayne Gostisbehere was unfit to practice for the Flyers on Saturday and will not be available for their intrasquad scrimmage Sunday.
Gostisbehere has spent part of training camp playing alongside Ivan Provorov on the top defense pair.
"We wanted to have the opportunity to take a look at 'Provy' and 'Ghost' together," coach Alain Vigneault said Friday. "They have played together in the past and my understanding is they've had some good success."
Provorov and Gostisbehere were paired together for long stretches during the 2017-18 season, when Provorov tied for the NHL lead among defensemen with 17 goals and Gostisbehere was fourth among NHL defensemen with 65 points (13 goals, 52 assists); they struggled to find the same success in 2018-19 and have rarely played together since then.
Gostisbehere, who played in 42 games last season, has said he feels better than in previous seasons following arthroscopic surgery on his left knee Jan. 14, and a similar procedure on his right knee in May. He is one of seven defensemen at training camp to play at least 40 NHL games last season, along with Provorov (69), Travis Sanheim (69), Erik Gustafsson (63), Justin Braun (62), Philippe Myers (50) and Robert Hagg (49). -- Adam Kimelman
