Lindgren (upper body) was skating with the regulars in a non-contact jersey during Friday's practice session, Vince Z. Mercogliano of USA Today reports.
Lindgren was placed on injured reserve ahead of the regular season due to an upper-body injury, and it's discouraging that he hasn't yet shed his non-contact jersey. It's not yet clear when he'll be able to return to game action, but a better idea of his return timetable could come into focus once he ramps up his workload in practice.
