Chargers tight end Hunter Henry was running sprints Friday at the start of practice, multiple media outlets reported.

Henry was wearing a brace on his right knee as he ran diagonal sprints, according to the Orange County Register. Henrys appearance at practice was unexpected given that he underwent surgery to repair a torn ACL less than four months ago.

It was assumed that Hunters injury, which occurred on the first day of organized team activities on May 22, was season-ending. He is on injured reserve but is eligible to return after Week 8.

The 23-year-old Henry was expected to be a focal point of Los Angeles offense in 2018. A second-round pick of the Chargers in the 2016 NFL Draft, Henry had 36 receptions and eight touchdowns as a rookie.

The former Arkansas standout recorded 45 receptions for 579 yards and four touchdowns in 14 games in 2017 before a lacerated kidney ended his season. His 12.9 yards-per-catch average was third best in the NFL among tight ends.

Henrys ascension led to the decision by the Chargers not to re-sign longtime standout Antonio Gates in the offseason. Gates returned to the club for a 16th season after agreeing to contract terms on Sept. 2.

In other news, Los Angeles wide receiver Travis Benjamin sat out Fridays practice because of a foot injury. Benjamin has not practiced all week.
