Schwartz suffered a ligament tear in his left knee during Friday's preseason loss to Tampa Bay, Barry Jackson of the Miami Herald reports.
Schwartz didn't play in either of the Dolphins' first two exhibition contests but was finally able to take the field Friday for the preseason finale. The 23-year-old caught both of his targets for 24 yards, but on his second catch -- a 17-yard reception thrown by Skylar Thompson -- he hurt his knee while being tackled. Jackson cites a source in indicating that Schwartz tore a ligament in his left knee on the play and suggests that the speedy wideout is headed either to IR or toward an injury settlement. Miami has yet to confirm those details, but this nonetheless appears to be another hit to a wide receiver room that has had its depth thinned due to a multitude of injuries.
