Both BJs are on the PUP. They are in the middle of a three week window (that ends November 9) where they are eligible to start practicing with the team. Once they begin practicing, the Texans have 3 weeks to make a roster move on them -- either to the IR for the rest of the season or onto the 53 -- or onto the practice squad if they are eligible. Ramon Walker was in the same situation and he started practicing this week.
The only suspense is if Joppru will start practicing next Wednesday. If he starts practicing, the Texans have three weeks to either activate him or put him on IR for the rest of the year.
I would expect Symons to not begin practicing during this window of opportunity and be moved to IR next week.
