Need a backup TE. Who should I drop?

I am looking to get a backup TE (Herndon). I currently have Marc Andrews and he is going on a Bye in 2 weeks, so I want to grab a TE now before they are all gone. My drop options are…
WR Dorsett
RB Mattison (Don’t really want to drop him)
RB Miles Sanders
RB Rashad Penny (I have Carson)
