Wednesday's OTA was closed to reporters, and a Ravens spokesman said the team will not give any reports from the workout. The severity of the injury is unknown, The Sun reported.
Campanaro is considered one of the leading candidates to return kicks for the Ravens, although the Ravens have been noncommittal in naming Jacoby Jones' successor. One reason is the Ravens want Campanaro to prove he can stay healthy before relying on him for a significant role. So, it's not a good sign that he couldn't get past the first day of OTAs.
Last year, Campanaro was limited in OTAs because of a hamstring injury and missed seven of the last eight regular-season games because of another hamstring issue. When he was healthy, Campanaro showed flashes as a slot receiver and finished with seven catches for 102 yards and one touchdown as a rookie. In the divisional playoff loss at New England, he caught all three passes thrown his way for 39 yards.
This injury is the latest setback for a player who had durability issues coming out of Wake Forest because of his small build. The Ravens wanted Campanaro so much late in the 2014 draft that they traded a 2015 sixth-round pick to Cleveland in order to acquire the Browns' seventh-round selection, which they used to take Campanaro. A hometown product, Campanaro played high school football at River Hill in Columbia, Maryland, which is 23 miles from M&T Bank Stadium.
