GLENDALE, Ariz. -- It's no secret football is a contact sport and whether you're 8 years old or in the NFL, football can sometimes hurt.
"It was his first year playing," Tiffani Allison said. "We waited his whole life for him to grow up and play football. He played three games and on the third game, he was tackled after the whistle blew."
Allison's son had severe arm injuries that took years to heal. Now, her grandson is getting ready to play so she's taking a crash course.
"I wouldn't want him to miss it," she said. "I would rather just be more knowledgeable."
The Arizona Cardinals hosted a camp for moms at the University of Phoenix Stadium. About 300 mothers got lessons on how to keep their kids safe on the field.
"Just like any sport, you have to know how to play it safely and with football there's so much equipment involved that if you don't fit it right, it really doesn't help you," Nicole Bidwill said.
Bidwill is sitting in, too, to learn about concussions on the field from Barrow Neurological Institute and how to ward off heat exhaustion from St. Joseph's Hospital.
The day wrapped up with Cardinals alumni demonstrating proper techniques on the field.
