From PFT http://profootballtalk.nbcsports.com/2017/10/24/devante-parker-returns-for-a-limited-practice/ ...Parker’s ankle was feeling well enough for him to take part in a limited practice on Tuesday...left tackle Laremy Tunsil on the field after he was listed as a non-participant on Monday...Defensive end Andre Branch and defensive tackle Jordan Phillips were also limited while center Mike Pouncey, running back Jay Ajayi, tight end Julius Thomas and right tackle Ju’Wuan James all went from a limited session on Monday to a full practice on Tuesday.
All good news. I read a similar article that said Parker wanted to play Sunday but they held him out as a precaution. Sounds like he's good to go if he didn't have any issues in practice today going full speed.
I'd say rest Parker if he's even close to not good to go. Let him get better for the Raiders, we'll need him more then.
