Los Angeles Chargers tight end Hunter Henry suffered a tibia plateau fracture to his left knee during the Week 1 win over the Indianapolis Colts, the team announced Wednesday, according to Andie Hagemann of NFL.com.
The Chargers have yet to determine a timetable for Henry's return but the team's initial expectation is a four-to-six week absence, a source told ESPN's Adam Schefter.
Henry, a former second-round pick, suffered a lacerated kidney late in 2017 and missed last season with a torn ACL.
When the 24-year-old went down in 2018, the Chargers re-signed franchise legend Antonio Gates to a one-year deal. The future Hall of Famer, who had 333 yards and two touchdowns last season, remains a free agent.
Henry's newest ailment likely explains why Los Angeles worked out former Oakland Raiders tight end Luke Willson on Tuesday, according to NFL insider Adam Caplan.
Okung will miss at least the first six weeks of the regular season after suffering a pulmonary embolism, while Gordon is holding out as he seeks a trade away from Los Angeles.
