Stock to be offered in Vernon Davis

Fantex Brokerage Services, a company that earlier this month announced its intention to sell shares of Arian Foster's future earnings, will announce Thursday that it hopes to do the same with San Francisco 49ers tight end Vernon Davis.

Fantex CEO Buck French told ESPN.com that the company will now have the rights to 10 percent of Davis' earnings, including his playing contract, endorsements and post career interests, after paying him $4 million up front as long as they can finance the deal.

The company says it will create a tracking stock that will enable fans to buy a piece of Fantex but specifically trade Davis' stock depending on how his brand is performing.

Davis signed a five-year deal with the 49ers in 2010 that gave him $23 million guaranteed. He is making $6 million in base salary this season.

The NFL veteran, who is in his eighth season in the league, is on pace to have a career year. He already has seven touchdowns and 518 yards receiving.

It hasn't been smooth sailing off the field for Davis, however. Earlier this month he lost an endorsement deal he had just signed after tweeting about a rival company. Davis re-signed for a second year to be a spokesman for coconut water brand Vita Coco, but the company dropped him after he tweeted about rival drink BodyArmor.

Davis has other endorsements with Force Factor sports supplements and beef jerky brand Krave.

French said Fantex will begin taking reservations next week on its interest in Foster, who was paid $10 million for a 20 percent stake in his future earnings. After an investor road show, and approval by the Securities and Exchange Commission, French said he hopes shares in Foster will be traded by late November.

Foster hasn't practiced since injuring his hamstring in a game against the Chiefs on Oct. 20.
