One domino effect of Lamb being injured is that it vaults Jalen Tolbert into a prominent role.

Tolbert did the bare minimum on the play, impeding Stevenson for a split-second initially to allow Williams to break free up the sideline.

Tolbert drew the ire of Cowboys fans in Week 1 when he left KaVontae Turpin out to dry on a quick pass out of the backfield.
