Jake Long managed to make a big impression on a couple of his rookie teammates in his first practice with the Miami Dolphins on Friday.

The Dolphins opened their three-day rookie minicamp on Friday 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."

COLTS: Indianapolis star receiver Marvin Harrison was interviewed by police about a shooting near his North Philadelphia bar 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 Friday. "Why he was interviewed, that is all part of the investigation. No one is a suspect."

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, a prep football star in Philadelphia, has owned Playmakers since July 2004, according to state records.

CARDINALS: Anquan Boldin says it's news to him that he's unhappy and wants out of Arizona.

To the contrary, the two-time Pro Bowl wide receiver says he wants to remain with the Cardinals and is not upset that he has yet to get a new contract on par with teammate Larry Fitzgerald .

"I've always wanted to be in Arizona," Boldin said Friday, the first day of the Cardinals' mini-camp.

Cardinals coach Ken Whisenhunt repeated the team's intention to re-sign Boldin.
