Ravens wide receiver Aldrick Robinson suffered a knee injury during an organized team activity practice Tuesday and was carted off the field, according to NFL sources.
The initial prognosis on Robinson is a sprained knee, per a source.
It was the second injury to a Ravens wide receiver this spring. Last week, Michael Campanaro (River Hill) suffered a partially-torn quadriceps and is sidelined until training camp.
Robinson was signed to a $660,000 reserve-future deal in January. He was signed to the Ravens' practice squad late in the season and made $10,000 per week, above the usual practice squad rate of $6,300.
