Striker Nabil El Zhar, 22, also limped off in the same game after spraining a medial ligament in his right knee, which will keep him out for four weeks.
Note: WR Stephen Hill, the team's second-round pick a year ago, is looking to bounce back from a disappointing rookie season in which he had 21 catches for 252 yards and three touchdowns, and ended up on injured reserve after spraining a knee ligament.
