No extension for Welker at deadline

As expected, the Patriots and receiver Wes Welker didn't reach an agreement on a contract extension by Monday's 4 p.m. deadline for franchise-tagged players, according to a source familiar with the negotiation.

As noted over the weekend, little momentum had been built to create an expectation of an agreement.

Welker will play the 2012 season under the $9.5 million franchise tag.
