Bergeron may make his first pre-season appearance Saturday. It will be his first game action since separating his shoulder, cracking his ribs, tearing rib cartilage and puncturing a lung in the Stanley Cup Final three months ago. If not Saturday in Detroit, then he's likely to play Monday.
This is a good sign that Bergeron will be ready for the Bruins season opener on October 3rd. It will take him some time to get back into game shape but expect him to be close to; if not 100% come October.
