WESTERN Bulldogs rebounding defender Jason Johannisen will miss at least 10 weeks with a high-grade right hamstring injury.
Johannisen does not require surgery. The hamstring tendon did not tear completely off the bone.
He suffered the injury when kicking a goal in the third quarter last Saturday night against Carlton.
