Jameis Winston was not at practice today. Andy Dalton took first team reps at QB, with Taysom Hill receiving reps as a reserve QB. This is different than past weeks.
Winston is dealing with broken bones in his back and the offense has struggled over the first three weeks. Keep in mind the Saints will fly to London to take on the Vikings this week in what will be a Sunday morning game. As the tweet said, it looks like the Saints are preparing in case they have to make a change at quarterback. Hill is dealing with a rib injury, but if he's good to go, and with Dalton under center, he could see increased time at QB - while being listed as a TE in a lot of leagues.
