There may be a glimmer of good news about wide receiver 
A medical re-check with Dr. James Andrews revealed that Perriman “may not have a significant ACL tear,” per ESPN’s Adam Schefter.
According to Schefter’s source, there is “absolutely” a chance that Perriman could return for the 2016 season, depending on the severity of the injury.
Perriman will still undergo surgery Tuesday to repair the tear, and once Andrews gets a closer look, he and the Ravens will know more.
According to NFL Network’s Ian Rapoport, Tuesday’s surgery will be minimally invasive and will determine whether Perriman will need full ACL reconstruction.
If Perriman doesn’t need reconstruction, he may reportedly just require a stem cell injection with the hope that the ACL heals on its own.
Typically, full ACL tears come with about a nine-month recovery. However, if Perriman’s ACL isn’t fully torn, there could be a quicker return.
The rate of Perriman’s recovery will be a key factor. The 2014 first-round pick suffered a partially torn PCL in his right knee last year and was slow to return to the field. After re-aggravating the injury, the Ravens eventually placed him on injured reserve.
Perriman also received a stem cell injection last year to help the PCL heal.
