MANKATO -- Vikings wide receiver Percy Harvin left the field Saturday on a cart after suffering an unknown injury during the Vikings' morning practice.
Harvin, the NFL's offensive rookie of the year last season, suffered a shoulder injury in 2009 but did not miss a game because of that problem. Harvin did miss several practices and one game because of migraine headaches.
The odd thing about what happened to Harvin on Saturday is no one saw him suffer an obvious injury. He did make what was perhaps the catch of the day in 7-on-7 drills when he bobbled a pass from Tarvaris Jackson but managed to catch the ball despite tight coverage from cornerback Asher Allen. Harvin's helmet popped off on the play as he made the catch, fell to the ground and then got up and tried to run.
Offensive coordinator Darrell Bevell said in his post-practice news conference that he didn't even know Harvin had left on a cart until told by a member of the media relations staff. Coach Brad Childress was not scheduled to speak to reporters after the practice.
Cornerback Benny Sapp also left on a cart during practice but he was able to return to the field and said afterward that he had just experienced some cramping problems most likely because of the heat.
The other storyline from today's practice was the abuse that second-round running back Toby Gerhart received. Although the Vikings were in shoulder pads and shorts, Gerhart took at least three hits that made it feel like a full contact day.
The first came from linebacker Chad Greenway in a 9-on-7 drill and the second and third came during 11-on-11 work. Nose tackle Pat Williams delivered an impressive hit that sent Gerhart flying near the end of a play after the rookie from Stanford caught a pass from Jackson. Near the end of that period, Gerhart was the intended target of a pass from Jackson but took a solid hit from middle linebacker Jasper Brinkley.
"It's expected," Gerhart said of the hits. "I feel like I'm playing football again."
