Alameda (CBS SF) — The NFL calendar may only read “Week 7” but the Raiders are well aware that they need to put a halt to their four-game losing streak if they want to get back into the playoff picture.

“We need a big win, and then we need to start stacking them,” Jack Del Rio said prior to Wednesday’s practice in Alameda.

Oakland hosts the Chiefs Thursday night at the Coliseum. Kansas City leads the AFC West with a 5-1 record.
