Tandler looks at Brandon Meriweather's recovery from a torn ACL:
Meriweather is still recovering from the torn ACL that ended his year early after a number of other knee issues forced his season to start late. That ACL injury occurred in the Redskins’ Week 11 game on November 18. If you do the math you have a recovery period so far of about eight and a half months.
The “normal” rehab period for a torn ACL is seven to nine months. It seems that Robert Griffin III will be recovered from his knee injury in closer to seven months while Meriweather needs more like the high end of the recovery range.
