Woods didn't practice Wednesday due to an illness, Jim Wyatt of the Titans' official site reports.
The nature of Woods' ailment isn't known, but if he misses a second day of practice Thursday, then it would add yet another layer of concern for his availability this weekend against the Chargers. While rookie first-round pick Treylon Burks (concussion) was sidelined for this past Sunday's loss to the Jaguars, Woods recorded five receptions for 49 yards on seven targets. He's now drawn seven or more targets in five of his 13 appearances on the season.
