Kaepernick's jersey a best-seller

Wearing a Miami Dolphins hat hasn't derailed Colin Kaepernick's ability to sell 49ers jerseys. The 25-year-old San Francisco quarterback's jersey was the biggest seller from April 1 to June 20, according to CNBC.com.

Two players with jerseys listed among the top 10 in sales have retired. Former Baltimore Ravens' linebacker Ray Lewis and former Chicago Bears' linebacker Brian Urlacher retired this offseason and are still outperforming active players.

Kaepernick, who was drafted by the 49ers in 2011, led San Francisco to the Super Bowl last season.

Here are the top-10 jersey sellers in the CNBC.com report:

5. Peyton Manning
6. Ryan Tannehill
