Former Iowa State linebacker A.J. Klein says a report he suffered a major knee injury at the combine on Monday is false.

The report surfaced after Klein fell in a position-specific drill that came after he posted a strong 4.66 time in the 40-yard dash. That had the Wisconsin native and 2011 Big 12 Defensive Player of the Year turning heads during the linebacker workouts, but caused concern after his stumble later on in drills.

He shelved the rest of the day's workout, but says there's no reason for concern and disputed the report that he had suffered a major injury, which would have certainly caused his draft stock to plummet.

"To everyone wondering about my little fall... All is good no serious injury," Klein tweeted.

He added he would complete his shuttle drills and log his vertical jump at Iowa State's pro day on March 26. He also plans to complete his position drills. In a later tweet, he said blamed the report on a bad source.

Klein, like his partner in crime at linebacker in Ames -- Jake Knott -- personifies what's good about college football and is a guy who works hard and stays out of trouble to pursue what he wants to do.

Here's hoping Klein is 100 percent when he gets a shot to show off for scouts next month.
