Kansas City, Mo. ? Dante Hall, one of the NFL’s most dangerous kick returners, has a hip injury, and his status is uncertain for this week’s game at Pittsburgh, Kansas City Chiefs coach Herm Edwards said Monday.

Hall had an MRI on his hip Monday, and the Chiefs were waiting for the results. The two-time Pro Bowler, who earlier this year got his 11th career touchdown return, was hurt while returning a kickoff in Sunday’s bruising come-from-behind 23-20 victory at Arizona.

“It might just be a hip pointer,” Edwards said.

Also out for the fourth straight game will be quarterback Trent Green, still recovering from a severe concussion he sustained in the season opener on Sept. 10.

Edwards said running back Larry Johnson was OK despite a frightening few moments when he lay motionless on the turf.

Johnson was grabbed by the face mask at the end of a 78-yard catch-and-run that set up Lawrence Tynes’ game-winning 19-yard field goal with 1 minute, 36 seconds to play.

“Larry was in today. He’s going to be fine but his neck is obviously sore,” Edwards said.

Hall, who also has become a favorite wide receiver target of backup quarterback Damon Huard, was replaced on punt returns by Eddie Kennison while rookie wide receiver Jeff Webb returned kickoffs. Edwards said those two would continue to fill in if Hall is out.

“Eddie does a good job of making decisions,” Edwards said. “That was a big-time play he made (in the fourth quarter) when he fielded that punt and got those extra four or five yards. Most guys don’t catch that ball and have the awareness to get what you can. Webb doesn’t know any better. He hits it like you’re supposed to hit it. He’s just following the wedge.”

Green went with the team to Arizona, his first road trip since he was knocked unconscious and taken away on a gurney. For the second week in a row, he offered suggestions and encouragement on the sideline for Huard.

But Edwards said he did not know when the two-time Pro Bowler would even start working out.

Doctors have said Green would be eased back into action, beginning with light workouts and progressing to full practice before he could think about getting back into a game.

“I would think shortly he’s going to start working out. I don’t know if that’s this week or next week or exactly when,” Edwards said.

It will be the fourth straight start for Huard, who has both delighted and surprised the Chiefs with the way he has performed.

He threw for 288 yards against Arizona, hitting seven of his first eight throws and rallying the Chiefs from a 10-point deficit with less than 10 minutes left.
