ST. LOUIS -- Rams wide receiver Dane Looker will have additional medical tests designed to rule out an aneurysm after a CAT scan that cleared him from a concussion revealed a brain abnormality.
Dr. Matt Matava, a team physician, said Looker would also be examined Thursday by a neurosurgical consultant to rule out other issues.
Team medical personnel believe the abnormality is unrelated to the concussion Looker sustained against the Buffalo Bills on Sept. 28.
"It could be something that concerns me, or it could be nothing as well," Looker said. "We're in limbo right now."
He said doctors believe the spot that showed up on the CAT scan has been there for some time, but one of the doctors' questions gave him pause.
"What made me a little nervous was he asked if I was married and if I had kids, and I said yeah," Looker said. "He said, 'We should get this done right away.'
"Anytime you're dealing with the brain, you start thinking about your mortality," he said.
Matava described the tests as precautionary, adding that Looker has had no symptoms or prior history suggestive of an aneurysm. Matava said an angiogram, in which dye is injected into the arteries, was a routine followup test that did not require immediate evaluation.
"There's no evidence he has an aneurysm, except that a suggestion of something like that showed up on one of his tests," Matava said. "It just needs to be ruled out."
The Rams (0-4) ruled out Looker for Sunday's game at Washington, although he sprinted with the rest of the team after practice. St. Louis re-signed wide receiver Eddie Kennison, who was released on Tuesday with the expectation that Looker would return to duty.
Looker is in his seventh season with the Rams and has six receptions for 108 yards and a touchdown and has served in past seasons as a punt returner and holder.
Coach Jim Haslett said the Rams had anticipated elevating another wide receiver, Derek Stanley, from the practice squad after releasing Kennison. Haslett said the Rams called the league office to try to void the release of Kennison but were too late, so he was re-signed to a contract and Stanley remained on the practice squad for another week.
"That was a strange one," Haslett said. "It's an unfortunate thing."
Kennison was signed Sept. 9 after Drew Bennett was sidelined with a broken foot in the opener and has played sparingly in two games, with no catches. He was originally a first-round pick of the Rams in 1996.
"In this business, I'm never surprised," Kennison said. "That's just the way it is. I was going home yesterday."
Kennison said he was unemployed for about six hours. He had planned to pack Tuesday night and driving back to his home in Kansas City on Wednesday.
"Yesterday was a character builder," Kennison said. "I'm here because it's unfortunate what's going on right now with Dane. I told Dane my prayers are out to him."
