Vikings quarterback Tarvaris Jackson left the field during this morning’s practice after appearing to trip over defensive tackle Letroy Guion during team drills. Jackson remained on the field for a few minutes as head athletic trainer Eric Sugarman and others attended to him but the quarterback was able to get up and walk off the field under his own power. Jackson’s issue appeared to be with his left leg. Source: Minneapolis Star-Tribune
