Analysis

Dobbs served as the 49ers' backup quarterback over Brandon Allen in Monday's 40-34 loss to the Lions, and the former saw the field late in the fourth quarter when Brock Purdy exited with an elbow injury. Dobbs proceeded to complete three of four passes for 35 yards and ran for a seven-yard touchdown on his five snaps. Purdy since has been diagnosed with a contusion and nerve inflammation in his throwing elbow, which is expected to sideline him for Week 18 action. Dobbs thus is in line for his first start of the campaign as the 49ers close out the season.

Analysis

Made active over Brandon Allen as the 49ers' No. 2 quarterback for Week 17, Dobbs was thrust into action with 1:45 remaining in the fourth quarter, when starter Brock Purdy was forced out of the game with an elbow injury. Dobbs proceeded to finish out the drive with a touchdown run, but the 49ers' comeback bid ended when the Lions recovered the ensuing onside kick. Per Matt Maiocco of NBC Sports Bay Area, head coach Kyle Shanahan said Tuesday that Purdy will likely be held out for Sunday's season finale in Arizona after an MRI revealed a contusion and nerve inflammation to his throwing elbow, but Shanahan was not willing to commit to whether Dobbs or Allen would draw the starting nod for Week 18. Shanahan told Maiocco that Dobbs' scrambling ability was a primary factor in the decision to keep him active ahead of Allen against the Lions, but Dobbs has otherwise been behind Allen on the depth chart all season.

Analysis

Dobbs will serve as Brock Purdy's backup for the second time this season, also operating as the No. 2 quarterback in Week 13 versus the Bills. Dobbs will take over that role from Brandon Allen (coach's decision), who will be available as an emergency third option in case both Purdy and Dobbs are knocked out of the game in Detroit.

Analysis

Dobbs is serving as the emergency third quarterback behind starter Brock Purdy and backup Brandon Allen, meaning he can't enter the game unless Purdy and Allen exit the game due to either injury or disqualification. The former Viking has yet to appear in a game this season, and he has been playing the emergency role for much of the campaign.

Analysis

Dobbs will serve as the emergency quarterback for Week 14, per Matt Barrows of The Athletic. Dobbs will only see the field Sunday if starter Brock Purdy and backup Brandon Allen were injured, sick or ejected.

Analysis

Dobbs will take a step up on the depth chart in Week 13 to serve as the No. 2 QB, supplanting Brandon Allen to take over the backup role behind Brock Purdy, who's officially active after missing Week 12 with a shoulder injury.

Analysis

Dobbs hasn't yet been active for a game this season with Brandon Allen working as Brock Purdy's backup. In order for Dobbs to get into Sunday's game against the Seahawks, both Purdy and Allen would need to be ruled out due to injury, illness or ejection.

Analysis

Dobbs will be the 49ers' emergency quarterback in Week 10. He'll only see the field Sunday if starter Brock Purdy and backup Brandon Allen are both forced to exit due to injuries.

Analysis

Dobbs will once again operate as the team's emergency quarterback in Week 8. He'll only enter the game if both Brock Purdy and Brandon Allen are forced to exit with injuries.
