Packers starting left tackle Bryan Bulaga indeed has a torn ACL, reports ProFootballTalk.com. If that's the case, Green Bay likely will shift Marshall Newhouse to left tackle, where he was barely adequate last year. The Pack then might have to start rookie David Bakhtiari at right tackle.
Bulaga's injury is bad news for Aaron Rodgers, who was sacked a league-high 51 times last year.
