Kevin Kolb managed to last a total of six plays in the Hall of Fame Game with the first team offense. Unfortunately, he erased no doubts and actually made concerns even worse. In his three drives, he was intercepted, had to scramble out of the end zone for an incompletion and then got hit and left with an injury.
He was intercepted on his first throw of the game, attempting to throw an "out" to Andre Roberts to the left. He was picked off by Malcolm Jenkins.
The second drive ended with a three-and-out. He threw two incomplete passes, the final being a throw-away while running away from pressure up the middle in the end zone.
His third drive lasted a play. He was pressured and got a throw away, completing it to Anthony Sherman, but he was hit as he went down and was injured. It was a rib contusion and he is doubtful for returning. Of course, being a preseason game, he will not come back.
Here is the play in an animated gif.
