The former second-round draft pick from BYU is slated to compete with former Heisman Trophy winner Troy Smith for the backup job behind starter Joe Flacco.
Six teams, including the Jacksonville Jaguars, expressed interest in Beck following his release from the Dolphins on Wednesday.
The pending transaction reunites Beck with offensive coordinator Cam Cameron, who recommended that Miami draft him when he was the Dolphins' head coach and started him in four games as a rookie during a 1-15 season that cost Cameron his job.
Beck was cut loose after the Dolphins drafted West Virginia quarterback Pat White in the second round. Dolphins executives Bill Parcells and Jeff Ireland and coach Tony Sparano never warmed to Beck after inheriting him from the previous regime.
Beck completed 60 of 107 passes for 559 yards, one touchdown and three interceptions with seven fumbles in five games during his rookie season as he posted a 62.0 quarterback rating. He didn't play in any games last season after going 0-4 as a starter as a rookie.
Beck is scheduled to take a physical, sign his contract and officially join the Ravens in advance of their Friday minicamp.
A two-time All-Mountain West Conference selection, Beck is a 6-foot-2, 216-pound California native and BYU's second all-time leading passer with 11,021 yards. He ranks third in touchdown passes with 79 behind Ty Detmer and Jim McMahon. As a senior, Beck passed for 3,885 yards and 32 touchdowns.
Beck's pending addition will give Baltimore five quarterbacks on the roster, including Flacco, Smith, recently re-signed veteran Todd Bouman, who's close to Flacco, and undrafted rookie free agent Drew Willy.
It's unlikely, though, that the Ravens will go to training camp with five quarterbacks.
This may spell the end of Bouman's tenure in Baltimore.
NOTE: The Detroit Lions announced that they have hired former Ravens Southwest area scout Jeremiah Washburn as their assistant offensive line coach.
A former Arkansas offensive lineman whose father, Jim Washburn, is the Tennessee Titans' defensive line coach, Washburn worked for the Ravens' scouting department for the past six seasons.
