Robinson was placed on the Texans' Physically Unable to Perform list Wednesday with an undisclosed injury, Aaron Wilson of the Houston Chronicle reports.
At this point in time, it's not well known what is plaguing the 25-year-old. Robinson signed a deal with Houston back in January with the expectation he would compete for a depth role at tight end, with most of his responsibilities likely to fall on special teams if he were to crack the 53-man roster. It seems as though Robinson's chances of making the team took a severe hit after he received the injury designation.
