The Ravens got bad news — but not terrible news — on Friday regarding Super Bowl XLVII hero Jacoby Jones. Per a league source Jones suffered a sprained MCL in his right knee during Thursday night’s regular-season opener. He’ll likely miss 4-6 weeks. The MCL is a rope-like ligament that becomes frayed when sprained. Most tears not involving complete severing of the ligament can heal with rest. Jones’ expected absence meshes with a Grade II MCL sprain which should heal without surgery. Jones suffered the injury after an accidental collision with teammate Brynden Trawick who ran into Jones while Jones was trying to catch a punt. It looked serious at the time with Jones’ knee hyperextending in ugly fashion upon impact.
