Defensive tackle Abdul Salaam is hurting and the New York Jets' Sack Exchange is back where it was last season, minus one stalwart.

The Jets thought they had the vaunted defensive line intact with 1981 all-pro Joe Klecko's recovery from major knee surgery performed early last season. But Salaam, an eight-year Jets veteran, came up with a shoulder injury that plagued him throughout preseason, and he was placed on the injured reserve list yesterday. The Jets claimed wide receiver Preston Brown on waivers from the Baltimore Colts.

Brown, a 1980 New England draftee, started the first four games of the 1982 season after spending all 1981 season on injured reserve. The 5-foot-11 receiver was claimed by Baltimore after the Patriots released him two weeks ago.

Among other NFL developments:

* In Chicago, the Bears waived seven veterans, among them offensive tackle Dennis Lick and safety Lenny Walterscheid, each a seven-year veteran. The Buffalo Bills claimed Walterscheid.

* In Cincinnati, the Bengals put running back Archie Griffin on the injured reserve list. Griffin pulled a groin muscle during the Bengals' exhibition game Saturday night against Detroit.

* In Pontiac, Mich., seventh-year running back Rick Kane ended his holdout by signing a multiyear contract with the Detroit Lions.

* In Kansas City, the Chiefs traded tight end Al Dixon, a seven-year pro, to Philadelphia for an undisclosed draft choice.

* In Los Angeles, the Rams acquired linebacker Mark Jerue from the Baltimore Colts in exchange for quarterback Mark Reed, whom they picked up on waivers from the New York Giants.

* In East Rutherford, N.J., running back Billy Campfield cleared waivers and was re-signed by the New York Giants.

* In Pittsburgh, the Steelers announced they had placed veteran quarterback Terry Bradshaw and tackle Tunch Ilkin on the four-week injured reserve list. Bradshaw is recovering from elbow surgery and Ilkin is suffering from strained ligaments in his shoulder.

* In St. Louis, the Cardinals released eight players, including veteran wide receiver Dave Stief.
