Albert Breer of NFL Network is reporting that, per league sources, quarterback Peyton Manning has informed clubs that he plans on making a final decision on his future on Monday or Tuesday.

He added the following:

People involved aren't convinced he'll stick to that, partially because the process has been lengthy already. We'll see what happens.

Today, it was revealed that the San Francisco 49ers were the "sleeper team" that was interested in Manning and joined the Denver Broncos and Tennessee Titans in the race for him.

Manning worked out for the Broncos today, but it was revealed that Manning had already secretly worked out for the 49ers on Tuesday, with coach Jim Harbaugh and offensive coordinator Greg Roman witnessing a passing session, and even underwent a physical exam by team doctors on Wednesday. According to ESPN, a sourced described the private workout as "very impressive."

The Arizona Cardinals and Miami Dolphins were informed that they were no longer in the race for Manning.

Manning and quarterback Alex Smith are both represented by agent Tom Condon, which may partially explain why Smith has not yet signed a contract with the 49ers.

Should Manning sign with San Francisco, that would make them the favorite to win the Super Bowl.
