The Patriots continue to weigh their options on the franchise tag as Monday's 4 p.m. deadline approaches.

No final decision has been made and the team will deliberate further on Monday, according to a league source.

The most likely candidates for the tag appear to be either right tackle Sebastian Vollmer or cornerback Aqib Talib.

Wide receiver Wes Welker is also a possibility, but progress has been made on getting a new deal for Welker. Also, tagging him will cost about $11.5 million because he was tagged in 2012.

Teams can continue to work toward a deal with a franchised player until mid-July. But once the tag is signed by the player, he's locked in for that one-year salary. The tag will be a little more than $10 million for both Vollmer and Talib.

The Patriots have about $25 million in room under the 2013 cap of $123.9 million.

The team appears to be leaning toward not using the tag but that is "not definite."
