Sean Lee and rookie J.J. Wilcox forced first-half turnovers for Dallas' revamped defense before the Oakland Raiders rallied past the Cowboys for a 19-17 victory in their exhibition opener Friday night.
Lee flattened Matt Flynn on a delayed blitz on the opening drive of the game to force a fumble deep in Oakland territory in his first action since a season-ending toe injury last October.
Wilcox intercepted an ill-advised pass from Terrelle Pryor in the end zone to thwart a promising Raiders drive.
The Cowboys forced just 16 turnovers last year, contributing to the firing of coordinator Rob Ryan, who was replaced by Monte Kiffin as the defense moved from a three-man front to a four-man front. Dallas has forced four turnovers in its first two preseason games under Kiffin.
