Dixon, 27, tried out for the team in April along with former Ravens starter Kyle Boller and Curtis Painter. The Ravens opted to sign Painter, who was cut Friday after an uneven preseason as the Ravens opted to go with two quarterbacks on their 53-man roster for the third straight year.
He's completed 35 of 59 passes (59.3 percent) for 402 yards, one touchdown and two interceptions. He also has one rushing touchdown.
The rest of the Ravens' eight-man practice squad is running back Anthony Allen, tackle Jack Cornell, guard/tackle Antoine McClain, linebackers Josh Bynes and Adrian Hamilton and safeties Anthony Levine and Omar Brown.
Allen, Cornell, McClain, Bynes and Brown were cut by the Ravens on Friday as the team trimmed their roster from 75 to 53.
Hamilton, a pass-rushing specialist who led the nation and broke a Southwestern Athletic Conference single-season record last year with 20 1/2 sacks for Prairie View A&M;, was cut by the Dallas Cowboys.
Levine was let go by the Green Bay Packers after spending the past two seasons on their practice squad.
