IRVING, Texas (AP) _ Dallas Cowboys defensive end Ebenezer Ekuban, the team's top pass rusher, will be sidelined for at least four weeks with a herniated disc.

Ekuban will undergo treatment in hopes of getting back on the field in a month. If he doesn't progress, he might need surgery.

``It's an injury guys have played with in the past,'' coach Dave Campo said Monday. ``It just depends on how he handles treatment.''

Ekuban missed much of the second half of Sunday's 10-6 loss to Tampa Bay because of the injury. He tried playing through it, but could hardly move _ a problem for anyone, but especially someone whose game is based on speed.

Peppi Zellner and rookie Demetric Evans will probably get the most action at Ekuban's spot Sunday against Detroit. Zellner, a ferocious hitter with great speed, is the better pass rusher; Evans is better at stopping the run.

The other injuries from Sunday's game were all on defense: Safety George Teague bruised his hip and sprained his left ankle, cornerback Izell Reese sprained his left ankle and linebacker Orantes Grant sprained his right ankle.
