SANTA CLARA -- Bob and George Whitfield joined the 49ers this week as part of the NFL's coaching internship program.

One of George Whitfield's responsibilities will be imparting upon Colin Kaepernick and the 49ers other quarterbacks some of the wisdom he has gleaned over the years as a quarterbacks guru of sorts.

"I thought it would be beneficial to us to have him here," 49ers coach Jim Harbaugh said of George Whitfield.

The Whitfields, who aren't related, arrived Monday. They are scheduled to work with the 49ers the rest of this week, all of next week and through training camp.

"We're really fired up to have them," Harbaugh said. "They're both doing a good job."

Bob Whitfield, an All-American at Stanford and father of current Cardinal receiver Kodi Whitfield, played offensive tackle for numerous years in the NFL. He has been assigned to work with the 49ers offensive linemen during his tenure.

George Whitfield has made a name for himself by working with quarterbacks such as Cam Newton and Andrew Luck before they reach the NFL draft.

Harbaugh said Whitfield will be just another voice in the 49ers quarterback room, along with quarterbacks coach Geep Chryst and offensive coordinator Greg Roman.

"There's no carte blanche," Harbaugh said. "We agree on a lot of things. I haven't found anything that we disagree on.

"It's not like we've turned our quarterbacks over to George, but he can augment it, he can assist, and it will be beneficial for us, beneficial for him, and it should be a win-win."
