DENVER -- Matt Flynn made his Raiders regular-season debut Monday night in a scenario he never could have envisioned in mid-August.
After starting quarterback Terrelle Pryor was knocked out of the game with a concussion in the fourth quarter, Flynn emerged from the bench after a Raiders fumble recovery and completed a 19-yard pass to Marcel Reece to the 1-yard line.
The play helped the Raiders get in the end zone one last time in a 37-21 loss to the Denver Broncos at Sports Authority Field.
"You've got to be ready at any time," Flynn said. "Obviously the game didn't go the way we wanted to. But I got in there, we had good field position and I was able to get it in, so we were fortunate in that aspect."
Flynn said it wasn't "the time or place" to discuss his demotion from the starting job he held through training camp, but he promised to be ready if the Raiders need him to start Sunday against the Washington Redskins.
Pryor must go through the NFL concussion protocol and be cleared to play.
"I'm always going to be ready," Flynn said. "That's one thing this team will never have to worry about is me being ready."
"It was just (Pryor) waiting on me to get open and being able to catch the ball and make a play when the opportunity was given to me," Moore said.
"It was a halfback pass, and we were able to catch them in the right defense and get it off," McFadden said. "I feel like I have a pretty good arm."
The Raiders opened in a nickel defense against Denver, with D.J. Hayden starting along with Tracy Porter and Mike Jenkins.
The Raiders promoted guard Lamar Mady from the practice squad to the 53-man roster, and he was active against the Broncos. Lucas Nix has been hobbled by an ankle injury, with Andre Gurode starting Monday night at left guard.
Mady was active over Antoine McClain even though McClain has been with the 53-man roster since the start of the season and Mady was promoted Monday.
Jeron Mastrud continued in his role as the Raiders' starting tight end, although it's been more of a two-man effort with rookie sixth-round draft pick Mychal Rivera playing on passing downs.
