ESPN's Adam Schefter is reporting Wednesday morning that the Buffalo Bills are one of three teams that have discussed the possibility of trading for Arizona Cardinals quarterback Matt Leinart.

The New York Giants and the Oakland Raiders are the other two teams Schefter mentions.

Leinart, tabbed this off-season to replace the retired Kurt Warner, has quickly fallen out of favor with Cardinals coach Ken Whisenhunt. Benched a week ago in favor of Cleveland castoff Derek Anderson, Leinart appears to have lost the starting gig he'd apparently been handed, and made some pointed comments about the situation late last week. FOX's Jay Glazer reported yesterday that Arizona had been actively shopping Leinart.

Leinart has two years remaining on the six-year, $50.8 million deal he signed as the No. 10 overall pick in 2006. Should a team trade for him, they'll pay Leinart $2.49 million in base salary this year. He's scheduled to make $7.36 million in 2011, and will also be due a $5.5 million roster bonus on the first day of the next league year. He has completed 19 of 23 passes for 161 yards and one touchdown this preseason.

Ryan Fitzpatrick and Brian Brohm are currently battling for the top backup spot behind projected starter Trent Edwards on Buffalo's depth chart. Time will tell if Buffalo's "discussions," if they even occurred, will prolong their apparent interest in Leinart.
