PRO FOOTBALL DAILY REPORT

Tight end Jay Novacek of the Dallas Cowboys is not recovering from back problems and could miss the entire season.

Trainer Jim Maurer said Novacek, 33, suffers from a degenerative disk in his lower back on which he had surgery in 1988 as a member of the Phoenix Cardinals. Novacek had two cortisone injections last week, but they did not reduce pain or swelling.

It will be the first NFL game involving a Baltimore team since December 1983.
