The 2013 salary cap is tentatively slated to be at or just below $121 million, according to NFL sources.

The values for restricted free agent designations and franchise tenders have also been set. Below are the tentative franchise tag and transition tag numbers for each position, in millions.

These figures were distributed in early December at the annual meeting of team owners in Dallas, reports NFL.com. They will likely be finalized in March.

CB: Franchise: $10.668         Transition: $8.939
DE: Franchise: $10.984         Transition: $8.994
DT: Franchise: $8.306           Transition: $6.919
K/P: Franchise: $2.926         Transition: $2.654
LB: Franchise: $9.455           Transition: $8.216
OL: Franchise: $9.660           Transition: $8.560
QB: Franchise: $14.642         Transition: $12.845
RB: Franchise: $8.079           Transition: $6.851
S: Franchise: $6.798             Transition: $5.899
TE: Franchise: $5.962            Transition: $5.105
WR: Franchise: $10.357        Transition: $8.716

With the deadline approaching for teams to slap the Franchise Tag on the player of their choice, things could get very interesting this weekend.

First, a look at the players who have already been tagged:

S Tyvon Branch - OAK
CB Trent Grimes - ATL
WR DeSean Jackson - PHI
RB Ray Rice - BAL
S Dashon Goldson – SF
DE Calais Campbell – ARI
K Mike Nugent - CIN
TE Fred Davis  - WAS

Here’s a quick run-down on some of the soon-to-be free agents who could get tagged should their respective clubs not reach a long term deal with them prior the March 5th (Monday) deadline.

CB Cortland Finnegan – TEN
QB Drew Brees – NO
RB Marshawn Lynch – SEA 
WR Wes Welker – NE
RB Matt Forte – CHI
WR Stevie Johnson - BUF
WR Dwayne Bowe - KC

That is 8 who have already been tagged and 7 more who most likely will, which brings the total up to 15. Some insiders believe that as many as 19 teams will use the franchise tag. Like I said, it should be an interesting weekend.
