Dan Henning got a one-year extension as the Atlanta Falcons' head coach and Marion Campbell will be back, too, this time as defensive coach. John Marshall, the team's defensive coach during this 4-12 season, is the man out of work.

"Although the record was not what we desired," Rankin Smith Sr., the team's owner said, "we feel Dan has handled an adverse situation as well as possible. The team played what may have been the most difficult schedule in the NFL and was beset by injuries, but continued to strive hard throughout the season."

The Philadelphia Eagles fired Campbell as head coach Dec. 16. He was an assistant for the Falcons in 1969-1974 and their head coach in 1975-76 . . .

The New England Patriots have offered five fans a special chance to buy hard-to-get playoff tickets. The five were burned when they tried and failed to carry the Patriots' goal posts under a 20,000-volt power line. The team wants to make the recuperating fans "feel better," a team spokesman said.

A city official in Foxboro called the offer "stupid" and wondered: "What's the town to do when (the team) rewards them?"
