Terrance Williams, Jason Witten's 2015 Fantasy Outlook After Tony Romo's Injury

Dallas Cowboys quarterback Tony Romo suffered a fractured left clavicle against the Philadelphia Eagles on Sunday, according to NFL.com's Chris Wesseling, which means players in head coach Jason Garrett's offense are about to be downgraded across the board for fantasy purposes.

Citing a source, CBS Sports' Jason La Canfora reported Romo is expected to be sidelined eight weeks—which comprises the majority of the fantasy regular season.      

With Dez Bryant already out for an extended period after undergoing surgery on his foot, wide receiver Terrance Williams and tight end Jason Witten have emerged as the Cowboys' most reliable targets.

The question now is whether backup quarterback Brandon Weeden will be able to feed Williams and Witten the ball with any sort of consistency. 

While an answer will remain elusive until we're exposed to a bigger sample size with Weeden under center, it feels safe to say the stock of both players is set to drop. That said, Williams' regression figures to be more dramatic than Witten's because of the fact that the tight end's conservative route tree is more conducive to adaptation. 

Romo and Witten have established tremendous chemistry, but if the 33-year-old can continue to eat up soft zones underneath and run intermediary routes that open him up for easy opportunities in the red zone, owners should be able to get away with starting him until the franchise quarterback makes a return. 

Williams, meanwhile, was a borderline fantasy starter to begin with, and it's hard to imagine owners trusting Weeden to find him for big gains week in and week out.

Although he could remain a matchup play in the weeks ahead—especially against the porous Atlanta Falcons and New Orleans Saints secondaries—trusting him to regularly put up starting-caliber numbers will be a mistake.
