Jake Long managed to make a big impression on a couple of his rookie teammates in his first practice with the Miami Dolphins yesterday at Davie, Fla.

The Dolphins opened their three-day rookie minicamp yesterday with 39 players, including Long, the first overall pick in the draft. On a simple running play toward the end of practice, the 6-foot-7, 315-pound tackle locked up defensive tackle Lionel Dotson, the Dolphins' seventh-round pick, and drove him to the ground.

Earlier, he showed off his mobility to fourth-round pick Shawn Murphy, a guard.

"We were doing foot drills and just watching his feet, he has great body control," said Murphy, the son of former Atlanta Braves slugger Dale Murphy. "He's tough, he's strong, he's got arms that are about 10 feet long. He looks like a power forward out there."

For Long, yesterday's practice represented an opportunity to begin showing why the Dolphins made him the top pick and gave him a five-year contract worth $57.75 million.

"There's definitely pressure," Long said. "I have that over my head every single day. That pushes me to go out and work as hard as I can and prove to people that I earned that No. 1 spot and earned the money."

Before Long went out for practice, Dolphins' head coach Tony Sparano said he wanted to see confidence, mobility and power from the big tackle this weekend.

"Just on first impression, I see him go through bag drills, I see him do some of those things," said Sparano, a former offensive line coach. "In individual (drills), you can see some flashes and some power ... but we have a long way to go here."

POLICE INTERVIEW HARRISON ON SHOOTING

Indianapolis Colts star receiver Marvin Harrison was interviewed by police about a shooting near his North Philadelphia car wash this week.

Lt. Frank Vanore said the investigation of Tuesday's shooting was continuing. Harrison has not been arrested or charged.

"He was interviewed," Vanore said yesterday. "Why he was interviewed, that is all part of the investigation. No one is a suspect."

Vanore told WCAU-TV the shooting occurred near 25th and Thompson streets, near a car wash owned by Harrison and about a half-mile from a bar also owned by the All-Pro receiver.

Earlier, radio station WIP, citing unidentified sources, reported the alleged shooting victim argued with Harrison at Playmakers bar. The victim left and headed to his car, Harrison followed and gunfire broke out, the station reported. The alleged victim was shot in the hand and did not identify the shooter, according to the radio station.

Harrison's agent, Tom Condon, denied the player was involved in the shooting.

ELSEWHERE

Eagles: Lito Sheppard reported for a mandatory minicamp last night, ending speculation that he might hold out until the Philadelphia Eagles trade him or give him a new contract. The two-time Pro Bowl cornerback landed on the trading block this offseason because he's unhappy with his contract. After the Eagles signed All-Pro cornerback Asante Samuel to a megadeal in March, it was assumed Sheppard would go elsewhere.

Vikings: The Minnesota Vikings want Kenechi Udeze to focus on his fight against leukemia and not worry about his financial situation. The defensive end was placed on the reserve-non-football-illness list yesterday, coach Brad Childress announced. That makes him ineligible to participate in the 2008 season, but guarantees him his $807,500 salary for the year. Udeze revealed two weeks ago that the cancer was in remission, and that his older brother has matching bone marrow for a pending transplant.
