Ravens HC John Harbaugh said the team wanted to give Lasley a chance to catch on somewhere else.
Lasley had been involved in a training camp fight earlier this week, but Harbaugh says that didn’t factor into the decision.
Lasley, 22, was drafted by the Ravens in the fifth round out of UCLA in 2018. He signed a four-year deal worth $2.7 million.
Lasley has yet to appear in an NFL game.
During his three-year career at UCLA, Lasley caught 113 passes for 1901 yards and 14 touchdowns in 23 games.
