However, missing Wednesday's practice is never a good way to start the week. While he is on track to miss Sunday's game versus the Jacksonville Jaguars, he could return on Thursday or Friday.
Fantasy Analysis: Keller is not the best fantasy option when healthy. Something like an ankle injury would affect the performance of a TE, so be wary of starting Keller on Sunday even if he's active.
Now would be the time to start looking for other options at the position, like Jared Cook or Scott Chandler. Keller owners would be wise to outsource another TE in Week 14.
