Gibson (knee/foot) didn't practice Wednesday, Ethan Cadeaux of NBC Sports Washington reports.
Gibson has been dealing with the foot injury for more than a month without missing a game, but the knee sprain he suffered Week 16 against San Francisco rendered him inactive for the Week 17 loss to Cleveland. With Washington having been eliminated from playoff contention, Gibson may be in line to sit out Sunday's season finale versus Dallas, though it's perhaps still possible he plays if he returns to practice Thursday or Friday.
