Doctors inspecting the potential damage to the brain of Rams receiver Dane Looker resulting from a concussion discovered an unrelated ”spot” on his brain.

Though the specific problem still isn’t known, the St. Louis Post-Dispatch writes that it could be an aneurysm.

“We don’t know for sure right now what it is,” Looker said Friday.  “I’m definitely not playing this week, but I’m hopeful about the future.”
