Cowboys QB Dak Prescott reportedly said he expected a decision following Saturday's practice on whether he'll start Sunday night against the Vikings. ESPN's Ed Werder, however, says 2 sources have called it a game-time decision. He quoted one as saying, "We are literally going to take it into tomorrow (night)." If it's truly a game-time decision for Sunday night, that would take the call beyond when most other QBs are starting their games. Waiting on Prescott will bring some risk this week.
