Rob Gronkowski continues to add to the speculation about a possible return to the New England Patriots.

On Sunday, Gronk took to Twitter to tease a "big announcement" coming Tuesday at 9 a.m. Later on in the day, the retired tight end posted a video to Facebook that is sure to get Patriots fans' hopes up.

In the video, originally posted by Tom Brady in 2016, the Patriots quarterback blows into a conch shell and adds a caption that reads, "New England Patriots RECEIVERS… ASSEMBLE!!!"

Gronk reposted it and asked, "Tom Brady, do you think this thing still works?!! 🐚"

Check it out below:

Gronkowski has always kept the door open for a possible return to football, but Pats fans shouldn't get too excited. Last month, Gronk seemed to shut down the idea of that comeback happening this season.

We'll just have to wait and see what the announcement will be on Tuesday. Gronk's deadline to come out of retirement and play again this season is Saturday, Nov. 30.
