#2 ran back onto the field 2 plays later in the same series. He was not attended to on the sidelines by any staff and never sat down.
#22 sprinted back onto the field after 3 plays in the same series. He, too was not attended to by any staff on the sidelines and never sat down.
#30 injured a shoulder and was taken off the field and attended to by trainers. He did not return.
We were behind the visitor's bench observing this "phenomena".
Everyone keep in mind that #2 was the guy who took 2 minutes from the time he was helped up and started for the sidelines to actually get off the field. The way he was walking we should have been fearing that his leg was going to fall off right there on the field. All the while Holgerson and his defense were enjoying a free time out after another ISU big play.
