Unable to reach a compromise after negotiations to try to restructure the contract of veteran fullback Vonta Leach, sources say the Ravens are expected to release or trade the Pro Bowl lead blocker as soon as Tuesday.
Ravens general manager Ozzie Newsome and vice president of football administration Pat Moriarty aggressively attempted to work it out with Leach, but were ultimately unsuccessful, a league source said.
Roughly an hour after The Baltimore Sun reported that he would be leaving the organization, Leach acknowledged the news via his official Twitter account.

"Thank Ravens organization for a great two years," Leach wrote. "I came here and did what we set out to do and that's win the Super Bowl. My time here is up but what we accomplished, we will forever be linked."
Leach was due a $3 million base salary and carries a $4.33 million salary-cap figure. So, the Ravens will save a total of $3 million against the salary cap while still carrying $1.33 million in dead money from the prorated portion of Leach's three-year, $11 million contract that included a $4 million signing bonus.
As the top fullback in the NFL, Leach is expected to be in heavy demand as a free agent with multiple teams expected to pursue him.
The Ravens won't have to search for his replacement after drafting Harvard fullback Kyle Juszczyk in the fourth round in April. At 6-foot-1, 248 pounds, Juszczyk still has to establish himself as a blocking presence in the NFL.
Juszczyk, who caught 125 career passes in the Ivy League for 1,576 yards and 22 touchdowns before excelling at the Senior Bowl, is expected to have a versatile, pass-catching role that includes lining up at fullback, tight end and H-back
Blocking for Pro Bowl running back Ray Rice for the past two seasons, Leach, 31, contributed heavily to the Ravens' running game.
Leach only played in 42 percent of the Ravens' offensive snaps last season and had 22 snaps during the Ravens' Super Bowl victory over the San Francisco 49ers. Few offenses in today's NFL feature an old-school fullback like Leach.
