Quarterback Matt Schaub is visiting the Ravens on Tuesday, according to NFL sources.
Schaub, 33, has also drawn strong interest from the Atlanta Falcons. The Dallas Cowboys and Tennessee Titans have also expressed interest.
The Ravens have been looking for a candidate to back up starter Joe Flacco. They have 2014 sixth-round NFL draft pick Keith Wenning under contract, but would ideally like to have an experienced veteran in place behind Flacco.
Former Ravens backup quarterback Tyrod Taylor signed a three-year, $3.35 million contract with the Buffalo Billls this offseason.
Schaub played for the Oakland Raiders last season after being acquired via a trade with the Houston Texans in exchange for a sixth-round draft pick.
Schaub was replaced as the starter by rookie first-round draft pick Derek Carr before being cut after the season.
In 11 games last season -- none of which he started -- Schaub completed five of 10 passes for 57 yards, no touchdowns and two interceptions.
A former Falcons third-round draft pick from Virginia, Schaub made the Pro Bowl in 2009 with the Texans when he passed for 4,770 yards, 29 touchdowns and 15 interceptions. Falcons offensive coordinator Kyle Shanahan was Schaub's offensive coordinator and quarterbacks coach in Houston.
For his career, Schaub has passed for 24,311 yards, 130 touchdowns and 86 interceptions with an 89.5 quarterback rating.
