Chark (chest/back) is listed as questionable for Thursday's game against the Dolphins, John Oehser of the Jaguars' official site reports.
Chark has been participating in practice on a limited basis this week, but the prevailing thought is that he'll be available Week 3. Either way, confirmation of the wideout's status will arrive upon the release of the Jaguars' inactive list approximately 90 minutes before Thursday's 8:20 p.m. ET kickoff.
