WILMINGTON — Captain’s practice continued for the Bruins veterans Thursday morning, but the attendance numbers were way down. A typical session has seen somewhere between 15 and 20 skaters with at least two goalies, but Thursday just seven guys on the ice total. They consisted of Nathan Horton, Gregory Campbell, Dennis Seidenberg, Andrew Ference, Blake Wheeler, David Krejci, and goaltender Nolan Schaefer. Krejci was the first one on the ice, and he spent the first few minutes out there with a crate of pucks taking wrist shots against the boards.
