Could Gavin Escobar's time be coming?

IRVING, Texas -- The Dallas Cowboys might be forced to become the two-tight end offensive team they thought they were going to be at the beginning of the season when they play the Washington Redskins on Sunday.

Hamstring injuries could keep Dwayne Harris and Terrance Williams from the field. Neither practiced on Wednesday but Williams is the more likely of the two to play.

The Cowboys signed Michael Spurlock, but he is more of a return specialist than receiver. The Cowboys have three receivers on the practice squad -- Tim Benford, Jamar Newsome, Lanear Sampson -- but it does not sound as if one could be called up for Sunday's game.

"We have [Gavin] Escobar and we have the tight ends that allow us to absorb some of that," coach Jason Garrett said.

If Harris and Williams can't play, then the Cowboys have only three healthy receivers in Dez Bryant, Miles Austin and Cole Beasley.

"Obviously that puts me in the game plan a little bit more, which is exciting for me," Escobar said. "I'm just ready to jump in there whatever the team asks for."

Escobar has only eight catches for 117 yards and a touchdown on the season. After having only one catch in seven weeks, Escobar has three catches for 47 yards in the last two games. He started against the Green Bay Packers.

"Every week I'm just trying to show the coaches I can make plays whether that's the scout team or on offense and I think the past few weeks I've been doing that," Escobar said. "I think their confidence is growing in me, so I'm just trying to translate that to game time."
