Kansas City, Mo. ? Safeties Shaunard Harts and Willie Pile were among seven players waived Tuesday by the Kansas City Chiefs, who were also putting quarterback Trent Green through an exhaustive battery of tests.

Coach Dick Vermeil said he was not sure Green would be able to play in the final exhibition game Friday night at St. Louis. At the same time, backup Todd Collins still is hobbled by a hand injury and might not be ready for the season opener Sept. 11 against the New York Jets.

Green has been bothered by numbness in his right foot and lower right leg. He played in only two series last week against Seattle before giving way to Jonathan Quinn, who was out of football when the Chiefs gave him an emergency call last week.

Vermeil said he would have a better idea of Green’s condition today.

“He’s going through a battery of tests. Some of these tests aren’t just five-minute deals,” Vermeil said. “They take sophisticated equipment and sophisticated people to administer. We’ll know a lot better tomorrow.”

Vermeil said he remained confident Green would be ready for the season opener.

“If he couldn’t play, it’s a big hurt. But we don’t anticipate that kind of evaluation, or findings when it’s all said and done,” he said. “I’m always concerned when you look out on the field and your starting quarterback’s not on the field, and he’s being given examinations.”

The Chiefs made nine player transactions to get down to 75 players. The 10 NFL Europe players on the team aren’t counted under the league’s requirement that squads trim their rosters to 65 by Tuesday.

Linebacker Shawn Barber, as expected, was placed on the physically unable-to-perform list, and fullback Robert Holcombe was put on injured reserved. Barber underwent major knee surgery last year.

Waived were punter Nick Murphy, wide receivers Nathanial Curry, Darrell Hill and Richard Smith, tackle Thomas Barnett and Pile and Harts.

Harts has seen considerable action the past four years and his release was something of a surprise.

“I hate to see those kids go,” Vermeil said. “Shaunard Harts has started like 17 games since he’s been here over four years. But that’s all part of this business.”
