The Raiders have optimism that Garoppolo will clear the NFL's five-step concussion protocol in time to play this Sunday against the Chargers, Jeremy Fowler of ESPN.com reports.

EDGE Analysis

Though he was able take every snap on offense in the Raiders' 23-18 loss to Pittsburgh this past weekend, Garoppolo was diagnosed with a concussion following the contest, with the injury likely stemming from a helmet-to-helmet hit he took from the Steelers' Minkah Fitzpatrick. Las Vegas will release its first Week 4 practice report later Wednesday, when it will be known whether Garoppolo made enough progress in his recovery from the concussion to practice in at least a limited fashion. If Garoppolo fails to clear the protocol prior to the weekend or is available only as an emergency backup if he fails to log enough practice reps in advance of the game, veteran Brian Hoyer would likely serve as Las Vegas' starting quarterback versus the Chargers.

Garoppolo has been placed in the NFL's concussion protocol, coach Josh McDaniels revealed Monday, Ian Rapoport of NFL Network reports.

EDGE Analysis

Garoppolo took a helmet-to-helmet hit from Minkah Fitzpatrick in the second half of Sunday's 23-18 loss to Pittsburgh, though it's unclear if that play was the cause of the possible concussion. The quarterback was able to finish the game but didn't attend post-game media sessions because he was being evaluated for a head injury. Those evaluations have resulted in Garoppolo being placed in the league's five-step concussion protocol. Garoppolo's progress through the protocol likely will be updated throughout the week, and if he's unable to return in time to face the Chargers in Week 4, Brian Hoyer would likely get the start, with Aidan O'Connell on hand to provide quarterback depth.

Garoppolo is being evaluated for a concussion following Sunday's 23-18 loss to the Steelers, Tashan Reed of The Athletic reports.

EDGE Analysis

It's unconfirmed when Garoppolo may have suffered the injury, but it is the second time in three weeks that the quarterback has been looked at for a potential head injury. Garoppolo played the entire game against Pittsburgh, completing 28 of 44 passes for 324 yards, two touchdowns and three interceptions. He took a helmet-to-helmet hit from Minkah Fitzpatrick in the second half, which was flagged for a roughing the passer penalty on Fitzpatrick. If Garoppolo is unable to clear the NFL's five-step concussion protocol before the team's next game, Brian Hoyer would fill in Nov. 1 against the Chargers.

Garoppolo completed 16 of 24 passes for 185 yards, one touchdown and two interceptions in Sunday's 38-10 loss to the Bills.

EDGE Analysis

Garoppolo orchestrated a touchdown drive on the Raiders' opening possession, completing all three of his passes for 45 yards, highlighted by a 16-yard connection with Davante Adams for the score. However, he was intercepted one drive later, and his day continued to spiral from there as he was unable to consistently connect with any skill-position players besides Adams and Josh Jacobs. Through two games in Las Vegas, Garoppolo has shown the ability to run the offense efficiently at times, but he's also turned the ball over three times.

Garoppolo (ankle) was a full practice participant Thursday.

EDGE Analysis

The Raiders haven't revealed whether Garoppolo's listed ankle injury is related to his surgically repaired left foot, but his upgrade from limited practice participation Wednesday to full participation Thursday erases any concern about his availability for Sunday's game in Buffalo. Garoppolo proved to be an effective game manager in the Raiders' 17-16 win over the Broncos in Week 1, committing just one turnover (an interception) while completing 20 of 26 pass attempts for 200 yards and two touchdowns to go with an additional nine yards on the ground.

Garoppolo (ankle) was listed as a limited participant in practice Wednesday.

EDGE Analysis

Garoppolo dealt with a foot injury prior to the season but looked spry in his Raiders debut, sealing a 17-16 Week 1 victory over the Broncos with an eight-yard scramble on 3rd-and-7 to get the game-clinching first down. It's unclear whether this ankle injury is connected to Garoppolo's prior foot problem, but regardless, it isn't expected to affect his availability Sunday in Buffalo, as Garoppolo indicated to Vic Tafur of The Athletic after Wednesday's practice that the quarterback is doing fine.

Garoppolo completed 20 of 26 pass attempts for 200 yards, two touchdowns and an interception in Sunday's 17-16 win over the Broncos.

EDGE Analysis

Garoppolo had a successful debut with the Raiders after signing a three-year, $67.5 million contract this past offseason. The 31-year-old looked healthy following offseason foot surgery, completing 77 percent of his passes and even taking off for an eight-yard scramble to extend a drive. Garoppolo got off to a good start against a tough defense, but he doesn't excite as a starter in fantasy. He will face another stiff test with his new club when the Raiders stay on the road to take on the Bills in Week 2.

Garoppolo completed all four pass attempts for 39 yards in the Raiders' 34-17 preseason win over the Rams on Saturday night.

EDGE Analysis

Garoppolo was in for the Raiders' opening possession and led a crisp nine-play, 68-yard march, during which he completed passes to four different targets. It was the veteran's official Raiders debut and, consequently, the first opportunity to prove his health after last season's foot issues. Garoppolo gave way to Brian Hoyer after that first drive as head coach Josh McDaniels clearly looked to limit his exposure, but it's certainly possible he gets more run in the preseason finale against the Cowboys next Saturday night.

Garoppolo is expected to start Saturday's preseason game against the Rams, Vincent Bonsignore of the Las Vegas Review-Journal reports.

EDGE Analysis

Garoppolo didn't play in the preseason opener, so this will be his Raiders debut. We shouldn't expect him to play more than a couple series, if that, and rookie Aidan O'Connell figures to lead the Vegas quarterbacks in snaps for this one. Garoppolo will look to knock some rust off in his first action since last season's foot surgery.

Garoppolo won't play in Sunday's preseason opener versus San Francisco, Tashan Reed of The Athletic reports.

EDGE Analysis

Garoppolo was suited up for warmups, but he'll ultimately watch the exhibition from the sidelines, along with WRs Davante Adams and Hunter Renfrow and TE Michael Mayer. The veteran quarterback's next chance to make his Raiders debut will come Saturday versus the Rams.
