The L.A. Rams officially opened the 21-day practice window for offensive linemen Steve Avila and Jonah Jackson on Thursday, meaning that the two players could start and of the next three games. If the Rams do not put either player back on the 53-man roster in 21 days, that player(s) will be out for the rest of the season.
The Rams play the Dolphins, Patriots, and Eagles in the next three games. Given how well Philadelphia has played recently, Sean McVay probably wants to be sure that he has both players available in Week 12.
