The Oakland Raiders have named Pryor the team's Week 1 starting quarterback, according to multiple reports.
Pryor, the Raiders' third-round pick in the 2011 supplemental draft, took the first snap with the first-team offense during a drill in the portion of practice open to the media Monday.
Oakland coach Dennis Allen said Monday afternoon that he would refrain from announcing a starter for "competitive" reasons.
The offense produced 32 points on 14 drives with Pryor at quarterback, compared to 10 points on 13 drives this preseason for Flynn. Flynn played mostly with and against starters, whereas Pryor was in mostly with second-team players.
Flynn, a six-year veteran, will serve as the team's backup, according to reports, a position he's familiar with.
Flynn has started only one game since the start of the 2011 season, a 31-of-44 performance in which he threw for 480 yards and six touchdowns and one interception while starting for the Green Bay Packers in place of Aaron Rodgers. On the strength of that game, Flynn earned a contract from the Seattle Seahawks prior to last season, but he lost out on the starting job in the preseason to then-rookie Russell Wilson.
The emergence of Wilson made Flynn expendable and the Seahawks dealt him to Oakland, where again he was presumed to be the team's Week 1 starter -- at least until Monday night.
