From ProFootballTalk.com:

The Arizona Cardinals have multiple trade offers for wide receiver Anquan Boldin and are close to determining which one they'll accept.

PFT has heard that the Baltimore Ravens, Kansas City Chiefs and New England Patriots are all interested in acquiring Boldin from the Cardinals.

Adam Schefter of ESPN reports that the Cardinals have spent much of Friday weighing their offers and determining which one to take. Schefter says that right now, the Ravens are the leading contenders.

Although it was reported this week that the Cardinals wanted a third-round draft pick for Boldin, it's possible that the presence of multiple bidders for his services has upped the price.

The 29-year-old Boldin had 84 catches for 1,024 yards and four touchdowns in 2009.
