The team then revealed that Prust was suffering from an upper body injury...which was expected to be a shoulder injury.
A few days later he began skating on a separate ice with a trainer. He went on the Californian road trip with the team and continued working on getting back into shape. Saturday morning (the day of their last road game for that trip) Prust showed up to practice with a contact jersey, meaning he was cleared.
Prust was given a few more days off to be able to skate with the team before getting back into the lineup.
On Tuesday morning the Habs practiced at the Bell Centre in Montreal (because Official Team Pictures were taken). During the practice Prust was on a line with Moen and White which indicates he will likely return on Wednesday night against the Bruins.
