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.
A sixth-round NFL draft pick of the Washington Redskins in 2011, the Southern Methodist product has caught 30 passes for 608 yards and five touchdowns in his career, including one pass for six yards in five games last season.
At SMU, Robinson ran the 100-meter dash in 10.49 seconds and 200 in 21.48 seconds and was an All-Conference USA honorable mention. At the NFL scouting combine, he ran the 40-yard dash in 4.35 seconds.
