There aren't many caller ID numbers one picks up for before 8 a.m. on a Sunday after the NFL draft. Cris Carter's is one of them.

The Vikings newest Pro Football Hall of Famer was overjoyed. His great year had just gotten a whole lot better. He said his former team would be signing his son, Duron, as an undrafted rookie free agent. It turns out it's actually an invitation to try out during the team's rookie minicamp this weekend.

"I'm just so happy for him that he'll get an opportunity to continue doing what he loves to do," Carter said. "For him to get that opportunity with the Minnesota Vikings, a team I played for and love, it's just a blessing."

Duron, a 6-4 receiver, caught 13 passes for his dad's alma mater, Ohio State, in 2009. But after becoming academically ineligible, he went to Coffeyville Community College in Kansas. He then transferred to Alabama and then Florida Atlantic, but never played for either school.

"Very few have taken the route to the NFL that he's taken," Carter said. "Minnesota presents the best opportunity for him."

So, dad, what are the kid's strengths?

"He has really good size, 6-4," Carter said. "Good speed and his route running is probably his strength."

And the hands? They're attached to a family tree that's believed to contain some pretty good hands.

"Rumor has it," said Carter. "His hands are good."

If he's signed at the end of the tryout and makes it to Mankato for training camp, Duron might have to ask for a few days off in August. He'll be Cris' Hall of Fame presenter in Canton, Ohio.

"This is why I'm not bitter about it taking so long to get into the Hall of Fame," Carter said. "It's perfect timing. It's a big year in my life. But it's also a big year in Duron's life. He's getting an opportunity to make a name for himself."
