The Flyers took to the ice for a Tuesday morning practice ahead of back-to-back road games in Chicago and St. Louis on Wednesday and Thursday. The lineup appears to remain the same as this difficult back-to-back takes place.

GM Ron Hextall provided an update on the team's injuries heading into Wednesday.

Both Nolan Patrick and Shayne Gostisbehere remain sidelined with upper-body injuries and will not make the road trip. The possibility remains that both could play on Saturday when the Flyers host the Colorado Avalanche, but nothing is certain yet. Both players skated on their own outside of the Flyers practice session on Tuesday.

Sam Morin was slated to get the callup with Gostisbehere injured, but a nagging injury was discovered ahead of Monday's game that forced him out of the lineup. The move was never processed on paper, meaning Morin is technically still listed on the Phantoms roster and not the Flyers. He will be out for at least a week and probably closer to two weeks with injury.

Mark Alt remains up with the Flyers and played 16:54 in Monday's game. The Flyers also had defenseman Will O'Neil at practice on Tuesday as an extra defenseman for the trip.

Hextall also updated Andrew MacDonald's condition. He is on schedule, the GM said, and will likely be nearing a return to the ice in three weeks.

The Flyers are on the road on Wednesday night against the Chicago Blackhawks and Thursday night against the St. Louis Blues. Both games begin at 8 p.m. They will return home on Saturday night at 7 p.m. to host the Colorado Avalanche.
