Chaisson (knee) is questionable to return to Sunday's game against the Texans, John Oehser of the Jaguars' official site reports.
Chaisson missed last week's loss to the Eagles with an ankle issue and was listed as questionable for this Week 5 contest, though he appears to have picked up a separate knee injury during the first half. The third-year linebacker played only 27 defensive snaps over the first three games of the season, but his absence will leave Jacksonville short-handed with fellow outside linebackers Jordan Smith (knee) and De'Shaan Dixon (coach's decision) both out Sunday.
