Alex Smith did the right thing in self-reporting concussion symptoms earlier this season, Roger Goodell said Friday, and the NFL commissioner said he hopes other players would do the same in a similar situation.

"I understand somewhat the dilemma, but the highest priority … is for players to raise their hand when they're injured so they can get the proper treatment," Goodell said during his annual Super Bowl news conference.

The dilemma, of course, is that Smith set in motion a series of events that ultimately cost him his starting quarterback job in San Francisco.

Colin Kaepernick started the next game for the 49ers against Chicago and played so well that coach Jim Harbaugh started Kaepernick over a healthy Alex Smith for the rest of the season.

Goodell noted that once Smith's concussion symptoms went away, it became a football decision and not a medical issue.

"The coaches made a decision to go in another direction," he said. "And that's something the coaches have to do."

Smith has said he has no regrets about telling team doctors about his concussion symptoms. They had gone away two days after the Nov. 11 hit against the St. Louis Rams that caused the initial concussion but reappeared one day before the Bears game on Nov. 19.

Here comes the son – Jim vs. John isn't the only Harbaugh family dynamic in the Super Bowl. There's also Jim vs. Jay – as in the 49ers' head coach and his oldest son.

After serving as an undergraduate assistant football coach at Oregon State, Jay Harbaugh is a coaching intern for John's Baltimore Ravens.

To this point, the Harbaughs have kept this part of the family narrative fairly quiet.
