SAN FRANCISCO (AP) _ Oakland Raiders running back Randy Jordan rejoined the team Friday, one day after an on-field collision during practice sent him to the hospital.

Raiders spokesman Mike Taylor said he did not know whether Jordan would play against the Rams in Saturday's preseason opener in St. Louis.

Asked about Jordan's physical condition, Taylor said, ``He's back with us, and the fact that he made the trip speaks for itself.''

The collision occurred during an intrasquad scrimmage. Jordan, blocking for quarterback Scott Dreisbach, collided with defensive end Regan Upshaw and linebacker Travian Smith.

Jordan, a seven-year NFL veteran, was conscious while lying on the field and in the ambulance on the way to a Napa hospital, where he underwent a battery of tests, including an MRI, Taylor said.

Taylor said he did not know the results of the MRI.

Jordan, 30, has spent the past two seasons with Oakland after a three-year stint with Jacksonville. Originally signed by the Raiders as an undrafted free agent in 1993, Jordan has been primarily a special teams player during his NFL career. He has rushed for 288 yards and three touchdowns, and has 215 receiving yards and one touchdown.

Jordan is third on the Raiders' depth chart at running back behind Tyrone Wheatley and Napoleon Kaufman.
