What happened: Caleb Tiernan remains week-to-week with an ankle injury. J.J. McCarthy participated in Monday's light practice after leaving Saturday's preseason game early.
Why it matters: The availability of Tiernan and Jackson will shape depth at tackle and safety as the 53-man roster deadline approaches. McCarthy's participation keeps the backup-quarterback evaluation moving before the preseason finale.
By the numbers: McCarthy took three hits and one sack across 18 snaps Saturday. The roster must drop from 90 players to 53 by 5 p.m. Sunday.
What to watch: Watch McCarthy's availability Friday and whether Tiernan or Jackson returns to team work before the Sept. 13 opener.
