ST. LOUIS — St. Louis Rams wide receiver Dane Looker is scheduled for additional medical tests after a CAT scan revealed a spot on his brain.

Looker said Wednesday that the abnormality is unrelated to a concussion he sustained against the Buffalo Bills on Sept. 28. The CAT scan cleared Looker to return from the concussion, but he won't practice until the current issue is resolved.

Looker has six receptions for 108 yards and a touchdown this season.

The Rams re-signed Eddie Kennison, who was released on Tuesday with the expectation that Looker would be fine. Kennison, signed Sept. 9 after Drew Bennett was sidelined with a broken foot in the season opener, has played sparingly in two games.
