Bengals DE Michael Johnson suffered a Grade 2 MCL sprain on Sunday, according to Pro Football Talk. The injury is expected to keep him out 4 weeks, which would put Johnson back on the field just before the start of the regular season. It's tough to imagine him being ready to start at that point. We'll see how the Bengals handle the DE spot opposite Carlos Dunlap. The injury looks particularly discouraging after a Week 1 ankle sprain seemed to derail Johnson's 2014 season in Tampa.
