Eric Cairns returned from his rehab stint in Wilkes-Barre and is with the team, but they're unsure of when he might play.
Ronald Petrovicky is practicing with the team as well, but there is no timetable set for his return.
Brooks Orpik has most of the strength back in his injured right hand, and he is accompanying the team on their west coast trip.
All three of these guys figure to be on the roster in the near future. This would mean that guys like Welch or Talbot could lose their spots, unless Shero has some trades up his sleeve.
