Brown (chest) is taking part in Tuesday's walk-through practice session and will have a chance to play in Thursday's game against the 49ers, Jim Wyatt of the Titans' official site reports.
While Brown remains on injured reserve, he's gearing up for a potential Week 16 appearance after the Titans cleared him to practice Monday, opening up a 21-day window for the team to evaluate him for activation. Until he's formally added back to the 53-man roster, Brown won't appear on the Titans' practice reports, making it difficult to get a sense of where he stands in his recovery from the chest injury that kept him out of the team's last three games. In order for Brown to be eligible to play against the 49ers, he'll need to activated by 4 p.m. ET on Thursday.
