Dallas Cowboys rookie WR Terrance Williams says he doesn't have a concussion and expects to play at Oakland

CANTON, Ohio – Dallas Cowboys rookie wide receiver Terrance Williams said he doesn’t have a concussion and expects to play in the second preseason game Friday at Oakland.

Williams suffered a blow to the head in practice Friday when he collided with cornerback Brandon Underwood trying to make a catch in a passing drill. Williams, the third-round pick from Baylor, was tested for a concussion and didn’t play in the first preseason game Sunday night against Miami.

“They were just being cautious,” Williams said. “I’m fine.”

Cowboys coach Jason Garrett also said he was optimistic that Williams could play Friday against Oakland, though he said he’s day-to-day.

“We don’t think what he has is a serious issue,” Garrett said.
