The Baltimore Ravens have agreed to terms with arena league quarterback David Olson, the NFL Network reported Thursday night.
The Ravens desperately needed another healthy quarterback after they began training camp Thursday without starter Joe Flacco, who is expected to miss a week because of a back injury. In the first practice of training camp, Baltimore used offensive assistant coach Matt Weiss to line up under center and hand off to running backs in drills.
Flacco notified the team about his back injury just before the first full-team meeting of camp, which didn’t leave the Ravens enough time to add a quarterback for the first practice. Olson will help spell Ryan Mallett, who has taken Flacco’s spot with the first-team offense, and Dustin Vaughan, who is on his fourth team in four seasons.
The agreement with Olson would not preclude the Ravens from adding Kaepernick.
Olson worked out for the team Thursday and will join the Ravens on Friday, according to the NFL Network.
He played under Harbaugh’s brother, Jim, at Stanford, where he was beat out by Andrew Luck for the starting job. He transferred to Clemson for his final season and most recently played for the KC Phantoms of Champions Indoor Football.
