The Ravens signed journeyman Josh Woodrum on Monday and waived David Olson, the Arena League quarterback who was added three days earlier. Woodrum will serve as the No. 3 quarterback behind Ryan Mallett and Dustin Vaughan until starter Joe Flacco returns from a back injury.
The move doesn't preclude the Ravens from signing Kaepernick or another experienced quarterback. On Sunday, Ravens owner Steve Bisciotti said the team was still considering Kaepernick and asked for fans to "pray for us."
Kaepernick, 29, has been a free agent since March 1, when he opted out of his contract with the San Francisco 49ers. He drew national attention last season when he knelt during the national anthem before games to protest social injustice.
After setting the Liberty University record for career passing yards, Woodrum was one of two FCS quarterbacks to participate at the 2016 NFL combine, along with Carson Wentz.
The Ravens also announced that receiver/punt returner Michael Campanaro passed his physical and will be activated off the physically unable to perform list. Campanaro, the team's primary punt returner at the end of last season, missed the first four days of training camp with a toe injury.
