NFL to Kaepernick, We Didn't Promise You Workout Attendance List!

5:45 PM PT -- The NFL says the league NEVER promised to give Kap's camp a list of people attending his workout on Saturday.

A high-ranking NFL source tells TMZ Sports, "It is completely false that the NFL had agreed at any point to provide a list of personnel executives and coaches that would attend Colin Kaepernick’s work out, simply we had interest as of yesterday at 4pm."

"We only started getting confirmations after the memo was sent to all teams. We can confirm that multiple teams have agreed to attend and hope Colin Kaepernick will accept the opportunity."

4:19 PM PT -- Sources tell TMZ Sports the NFL will NOT be providing a list of team personnel planning to attend the workout on Saturday. We're told the NFL initially said they would give Kap's camp the list, but now they have reversed course. Unclear why.

We have been told multiple teams have reached out to Kap's camp to inform them they would not be attending the workout. Apparently, the teams wanted to be open and honest about it in case stories came out saying otherwise.

There have been several teams who have said they'll attend the workout, but it's unclear if they're sending high-level execs as requested or regular scouts.

1:49 PM PT -- Belichick didn't have the answer ... but now we know the Patriots WILL have a rep at the workout on Saturday. New England is sending a scout (not a head coach or GM, like Kap asked, but still).

10:59 AM PT -- Panthers safety Eric Reid -- one of Kaepernick's biggest supporters -- says the workout "feels like a PR stunt" by the league ... but says Kap will be ready for it regardless.

"We'll see if it's a real process," Reid says. "We'll see if it's a real event."

9:41 AM PT -- The Detroit Lions WILL send reps to Colin's workout, says coach Matt Patricia.

"As an organization, we always do our due diligence on all players that are available ... so I know [Bob Quinn] and his staff will have someone down there to watch the workout and we’ll see where that goes."

Other head coaches are weighing in on the workout at their Wednesday meetings with the media ...

The Atlanta Falcons say they ALSO plan on having someone at Kap's workout. Not a surprise because the workout will take place at the Falcons facility.

Denver Broncos -- Vic Fangio says he's unsure if the team will be in attendance.

Houston Texans -- Bill O'Brien declined to comment on whether or not the team will be in attendance.

Chicago Bears -- Matt Nagy says the team is not sure if they'll have a rep in attendance.

Indianapolis Colts -- Frank Reich says the team hasn't made an official decision yet.

Baltimore Ravens -- John Harbaugh says he does not know if the team will have a representative at the QB's workout.

Dallas Cowboys -- Jason Garrett says he's "not really in tune" with Kaepernick's situation and is unaware if the team will send a rep to the workout.

New England Patriots -- Bill Belichick says he's "not sure" if the team's interested ... and said to check with Nick Caserio, the director of player personnel.
