Running back Herman Hunter became the third player to leave the Philadelphia Eagles' training camp in as many days.

Coach Buddy Ryan said Hunter, who was the club's kickoff returner as a rookie last season, left camp after meetings Sunday night.

"He wasn't blocking in any of the drills," Ryan said. "I assumed that when the linebackers started blitzing, he'd leave."

Hunter, who averaged 21.8 yards per kickoff return, joins guards Steve Kenney and Greg Naron as Eagles who have departed camp without permission. Kenney left Saturday after he was demoted to third string and Naron, who had been a starter, joined him on Sunday.

Ryan said that although all three players are welcome to return, he was not going to expend any effort to get them back.

"I don't talk to people like that," he said. "When a guy goes home or quits, there's always going to be a doubt in your mind that in the fourth quarter someday, they'll go home again." . . .

Miami Dolphins quarterback Dan Marino reported to training camp on time, thus earning the easiest $850,000 of his career -- an appearance bonus.

Last year, Marino walked out of camp after three days and stayed out 37 days to protest the lack of progress in the renegotiation of his contract. Marino's original four-year, $2 million deal, which included the huge appearance bonus, expires Feb. 1 . . .

Investigators from the county coroner's office in Sacramento, Calif., closed their case on Cleveland Browns star Don Rogers, concluding he had a healthy heart with no sign of long-term drug use when he died of a cocaine overdose on June 27 . . .

At the USFL-NFL trial in New York, a former NBC-TV producer contradicted the head of the network's sports department, saying he was told to ignore USFL scores and stories on the sports news show he ran.

But the witness, Matthew McCarthy, acknowledged that he was not aware of all the stories on his show, including one about six stars who had signed with the new league.

McCarthy was the only rebuttal witness called as the USFL's $1.69 billion antitrust suit against the NFL began its final week.

McCarthy said that as the producer of the NBC weekend show "30 Rock," he tried several times before the show went on the air in spring 1983 to get his bosses at NBC to make a decision on whether to carry USFL stories and scores. Finally, he said, he got an answer from Arthur Watson, the president of NBC Sports. "Arthur said, 'We're going to ignore the USFL,' " McCarthy testified.
