The St. Louis Rams' long search for a return man ended yesterday when the team acquired Dante Hall from Kansas City for a fifth-round pick in this weekend's draft.

The trade could have draft-day implications. The Rams had expressed strong interest in Ohio State's Ted Ginn Jr., as much for his return ability as for his resumé as a receiver. St. Louis also has several needs on defense.

As part of the trade, the teams swapped positions in the third round - the Chiefs moving up to 82d overall, the Rams down to 84th.

The 28-year-old Hall has returned 11 kickoffs and punts for touchdowns in his seven-year career, including four (two kickoffs, two punts) in 2003. Former Eagle Brian Mitchell holds the record with 14 kick-return touchdowns, followed by Eric Metcalf with 12.

Hall also needs one more kickoff return for a touchdown to break the record of six he shares with Ollie Matson, Gale Sayers, Travis Williams and Mel Gray.

Goodell issues warning. NFL teams will be disciplined by commissioner Roger Goodell if they leak confidential information from interviews with prospective players.

Goodell sent memos to the 32 teams Tuesday warning them that all interviews should be considered confidential, and that clubs will be disciplined for conduct detrimental to the league if there are any leaks.

A recent story in Pro Football Weekly identified Georgia Tech receiver Calvin Johnson, Clemson defensive end Gaines Adams and Louisville defensive tackle Amobi Okoye - three top-rated prospects for Saturday's draft - as acknowledging they had experimented with marijuana.

That report cited unnamed club officials and said the information came from videotaped interviews at February's NFL combine.

Goodell also has asked for a review of interviewing procedures at the combine. He has not yet determined what sort of discipline will be implemented for leaked information.

Titans. Cornerback Adam "Pacman" Jones' trial in Georgia on a felony charge of obstruction has been delayed.

Jones, given a season-long suspension by Goodell, was scheduled for a May 14 appearance in a Fayette County courtroom stemming from a February 2006 incident.

Jones was arrested in Fayetteville, Ga., after getting into a physical argument with a patrolling police officer.

Fayette County District Attorney Scott Ballard told the Tennessean newspaper of Nashville that the case won't be heard until at least September.

Raiders. Oakland released defensive end Lance Johnstone and offensive lineman Brad Badger, and signed defensive tackle Josh Shaw and defensive back Kris Richard.

The moves were made late last week but not announced until yesterday.

Oakland also waived receiver Leo Bookman.

Lions.

Detroit signed wide receivers Marcus Robinson and Cliff Russell and re-signed cornerback Keith Smith.

Dolphins. Miami re-signed linebacker Donnie Spragan to a one-year deal for undisclosed financial terms.
