SIDELINED: Pittsburgh safety Tom Everett suffered a gruesome injury in the closing minute of the first half against Cleveland. After catching a knee in the helmet from the Browns' Kevin Mack, he remained prone on the field for about 15 minutes while being treated by doctors and trainers.

He suffered a severe concussion, but the smallish defensive back (5 feet 9, 178 pounds) also had a lacerated forehead. Everett had to be held down, reportedly after panicking upon feeling blood stream down his face. But the cut was only superficial. No word if he'll play next week. . . .

Meanwhile, Mack will have his broken left ring finger examined today. He broke it late in the first half. Team spokesman Kevin Byrne said Mack may play as soon as next week if a pin can be inserted into the bone. Otherwise, it could be several weeks.

NO VALUE ADDED: Emmitt Smith, a first-round pick from Florida, made his debut with the Cowboys with only three days of practice. A holdout for a club-record 48 days, he rushed two times for two yards. . . .

Dallas linebacker Eugene Lockhart broke a string of double figures in tackles. He reached at least 10 every game in 1989, but had only five against San Diego.

RECORD KEEPING: Bengal Jim Breech's three field goals and two extra points against the Jets moved him within one game of tying an NFL record. He is one game behind Fred Cox's scoring record of 151 consecutive games. Breech needs 19 points to become the 16th player with 1,000. . . .

Al Toon of the Jets extended his streak of consecutive games with a catch to 62. . . .

The Colts kept a dubious streak alive: They haven't won an opener since moving to Indianapolis in 1984. . . . Jim Kelly's three-yard scoring pass to Butch Rolle was the 1,000th touchdown in the Bills' 31-year history. Rolle's last six receptions have gone for touchdowns. . . . Colt Stanley Morgan's 25-yard scoring catch moved him into fifth place all time in receiving yards, 10,377.
