[Topeka Capital-Journal] The Chiefs seemed less certain about the health of quarterback Trent Green on Tuesday than they did 24 hours earlier.

Green did not practice Tuesday while undergoing yet another battery of medical tests to determine the cause of numbness in his lower leg and foot.

Coach Dick Vermeil, just a day after saying that previous tests showed no medical reason for the problem that forced Green to the sideline early in last week’s Seattle loss, could not say whether Green would play in Friday’s preseason finale in St. Louis.

“We’ll know more (today),” Vermeil said. “We’ll either have an answer, or the answer will be that there’s nothing wrong.”

If Green cannot play in the finale, Kansas City has only Jonathan Quinn, who joined the team only last Tuesday, and rookie James Kilian as healthy quarterbacks.

Backup Todd Collins did some light throwing with his fractured right hand Tuesday but said he is not ready to throw in a game. Damon Huard still has not been cleared to play after sustaining a concussion in the Arizona game.
