The sweepstakes for signing former Oakland Raiders cornerback Nnamdi Asomugha is down to two teams: the Dallas Cowboys and the New York Jets. 

According to sources cited by NFL.com, the San Francisco 49ers have dropped out of the picture, leaving the Cowboys and Jets as the primary suitors.

Asomugha, who is currently a free agent, has been one of the top cornerbacks in the league since being drafted by the Raiders in the first round of 2003. He has been a four time All-Pro and Pro Bowl selection.

At 30, Asomugha is considered to be in the prime of his career and will likely command a substantial salary -- certainly more than the $15 million he made with the Raiders over the past two years.

The Cowboys and Jets are both in need of a premier cornerback. Interestingly, if he signs with one of these two franchises, Asomugha will be taking orders either from Dallas Cowboys defensive coordinator Rob Ryan or his twin brother, outspoken Jets coach Rex Ryan -- who has already vowed to take Gang Green to the Super Bowl next season.
