According to the Denver Post, the San Francisco 49ers are one of nine teams that are expected to at least inquire about a trade for Denver Broncos wide receiver Javon Walker.

The other teams include Tampa Bay, Dallas, Washington, Tennessee, Pittsburgh, Carolina, Chicago and the New York Jets.

Deals can't be finalized until next Friday. Walker has a big contract and a history of knee issues. Any deal involving Walker would likely involve a conditional draft pick. If he's not traded by March 4, Denver will likely cut Walker, who is due $5.4 million in bonuses.
