Brown, however, was expected to be back at the team's practice facility on Saturday, according to head coach Mike Tomlin, and it appears that has happened.
If Pittsburgh can put the Jaguars run game in check early and force Jacksonville quarterback Blake Bortles to beat them with his arm, the Steelers have a real shot to win and move on to the AFC title game.
Brown was listed as questionable to play in Sunday's divisional-round playoff game on the team's official injury report released Friday afternoon.
This comes just a couple of days after Brown was a full participant in practice for the first time since suffering the torn calf in Week 15 against the New England Patriots. "We do need to get him well from an illness standpoint". They completely shut down the Steelers' run game and when they turned to the passing game, the Jaguars harassed Ben Roethlisberger and forced mistakes. "We'll bring him back in the building tomorrow and continue on with his game readiness but I really don't have a lot of reservations from a physical health standpoint", Tomlin said. "Today, I sent him home with an illness".
