Goff seemed fine to teammates in the aftermath of that game, but would have to pass several tests before being deemed ready to play under the NFL's concussion protocol.

According to the NFL, Rams' interim head coach John Fassel is considering demoting Case Keenum to get Mannion some needed reps.

Having defensive tackle Aaron Donald and punter Johnny Hekker selected to the Pro Bowl is a good start, representing defense and special teams units that have mostly played well, but getting quarterback Jared Goff and the offense on track is the main goal.

Rams rookie quarterback Jared Goff has been cleared from the league's concussion protocol and will start Saturday's game against the 49ers.

"Obviously that would be a great opportunity for me", Mannion said.

"I'm always ready to go in the game and win".

Mannion was the 89th overall pick out of Oregon State in 2015, finishing his collegiate career as the Pac-12's all-time leader in passing yards, a record previously held by USC's Matt Barkley. Mannion came on in relief of benched starter Nick Foles and completing 6-of-7 passes for 31 yards against the Cincinnati Bengals.

"I feel like I've made huge strides". "I got up, went back to the huddle, and I hear the official blowing the whistle - 'You've got to get off the field.' I'm like, 'Why?' They said it was just the protocol".

"He was really strong previous year in the second half because we were playing in close games, that's when he popped a lot of those", Boras said.

The Rams have already made some other moves with an eye toward the future, deciding to exercise caution with defensive end Robert Quinn by placing him on injured reserve last week and signing four players to the practice squad this week.

Mannion began this season as the backup, but that was only because the Rams were bringing Goff along slowly.

What makes those issues all the more confounding is that the Rams insist every week they are practicing well going into the game, only for that preparation not to carry over.
