The Ravens had backup quarterback Ryan Mallett in for a workout Wednesday, Head Coach John Harbaugh confirmed.
Harbaugh didn't want to comment on how the workout went or whether the Ravens will sign him. Baltimore signed Jimmy Clausen to be Matt Schaub's backup last week.
"He was here working out," Harbaugh said of Mallett. "We'll see where those things go as we move forward."
Mallett was released by the Texans in October after missing the team's charter flight to Miami for a Week 7 game. He lost his job after being Houston's starting quarterback just two weeks earlier.
Mallett, 27, took over for Brian Hoyer in Week 1 when Hoyer left a game against Kansas City due to injury. Mallett went 1-3 as the Texans' starter. He threw three touchdowns to four interceptions and logged a 63.6 quarterback rating.
The 2011 third-round pick out of Arkansas backed up Tom Brady for three years in New England before being traded to Houston. He started two games in 2014 in which he threw two touchdowns and two interceptions with a 67.6 passer rating. He went 1-1.
The 6-foot-6, 245-pound gunslinger is known for his very strong arm.
