Gronkowski appeared to suffer an injury during 7-on-7 drills where he pulled up on Tom Brady’s pass in Gronk’s direction. The Patriots tight end walked over to a trainer, who eventually escorted Gronkowski off the field. Gronk walked off under his own power, but was moving slowly as he exited to the rear of the field.
Information about the injury is scarce at the moment, but given Gronk's injury history, it seems worthwhile to pass along the report from Boston.com. We don't recommend Gronkowski in the 1st or 2nd round this season due to the good depth at his position.
