Free agents for Bills/Titans game

Anyone know for Yahoo if available free agents in the Bills vs Titans game will go on waivers tonight or will be available for pickup tomorrow? I needed to pick up Drew Brees as a replacement player for Josh Allen in case the game gets canceled. But if it is played, I’d like to drop Brees and pick up a WR since Mike Thomas is an idiot and I don’t have anyone else left to play at WR.
