Leonard Tose paid $1.75 million to stop the $42 million sale of his Philadelphia Eagles to which he agreed three months ago and, after that settlement yesterday in Delaware County (Pa.) court, Tose was "reasonably happy" and would-be buyer Louis Guida "very happy."

Guida and partners Ira Lampert, Dr. Julius Newman and Sandra Newman sued when Tose tried to cancel a June 17 promise to sell them his 99 percent of the NFL team. They would have paid $33 million in team debts and $9 million of personal debts run up by Tose, who bought the Eagles for $16 million 15 years ago.

The proposed purchasers were to have paid Tose a retainer salary and provide his daughter/general manager, Susan Fletcher, 20 percent interest in the club. Now, says Guida, "Anytime you can put up a total of $400,000 (the sale deposit) and end up with $1.75 million, you have to be satisfied" . . .

"Definitely a cheap shot," Denver Coach Dan Reeves says of a forearm strike that knocked off rookie quarterback John Elway's helmet at the end of a 19-yard scramble Sunday. NFL officials will review film to see if it merits discipline against Eagle Wes Hopkins, the tackler in question . . .

The Bills have countersued seeking to prevent Joe Cribbs from joining USFL's Birmingham Stallions next spring; Buffalo claims, opposite Cribbs' own suit, it has contractual right of refusal to match any offer . . . In Dallas, Coach Tom Landry has named Doug Donley (six catches, 88 yards vs. Giants) to start against the Saints if Tony Hill (sprained arch) can't play. And, Landry allows that Butch Johnson, who normally would get the call, is "depressed" . . .
