Risto has suffered a setback with his latest injury.

After a few weeks of hard work and continuous coaching, it appeared that Risto began to click with the system and started to fulfill the expectations the Flyers had for him. However, in the current season, Risto has been unable to suit up due to an undisclosed injury that occurred before the season began.

It appears that he has experienced a setback from his injury, which has rendered him unavailable for the Flyers in the foreseeable future. Tortorella explained the Flyers' situation regarding his injury.

Risto's contract will remain on the injury reserve list, allowing the Flyers to recoup $5.1 million in cap space. It is widely expected that the Flyers will not spend that money, as it will be needed if Risto can return to the lineup once his injury clears.

However, if the injury turns out to be truly devastating, and he is unable to return, much like Ryan Ellis, the Flyers may seek defensive help as they continue to build their roster.

Flyers fans certainly hope for Risto's speedy return, as he has become a key figure in their defensive core and is considered a top-four defenseman. Time will tell whether he can make a comeback.
