Niners DT Franklin will play under franchise tag in 2010

The San Francisco 49ers will not sign defensive tackle Aubrayo Franklin to a long-term deal by Thursday's deadline, according to a team official. Therefore, Franklin will play next season on a one-year, $7.003 million salary as a franchise-tagged player.

The 49ers hoped to lock up Franklin to a long-term contract before the deadline, and there has been dialogue between both sides. However, a 49ers official said there is "no chance" an extension could be completed before Thursday.

Depending on the future collective bargaining agreement, Franklin could be designated a franchise player again in coming seasons. Regardless, the 49ers aim to secure Franklin's services past 2010, but they won't be able to do that until after the season.

Franklin, a seven-year NFL veteran, has spent the past three seasons in San Francisco. He started his career on a four-year stint with the Baltimore Ravens.
