Vikings waive AC Leonard

MANKATO, Minn. -- The Minnesota Vikings announced on Wednesday afternoon they waived tight end AC Leonard, parting ways with a promising undrafted free agent who hadn't practiced since July 30 with what coach Mike Zimmer initially called a headache.

Zimmer has said Leonard didn't have a concussion, from what he understood. "He’s going through some of the tests, but from what I understand, it wasn’t," he said. "I don’t know. He’s had headaches. It was basically just the one day."

The Vikings did not release Leonard with an injury designation, which means he must have been cleared medically before the team let him go. His departure, however, leaves the team a bit thin at the tight end position. Chase Ford is still working his way back from a broken foot, and other than Kyle Rudolph, Rhett Ellison is the Vikings' only tight end who has played more than 20 NFL games.
