The long-awaited return of DeAndre Levy will likely be delayed another few days.

Despite practicing for the third day in a row on Friday, Levy was listed as doubtful for the Detroit Lions’ game against the Jacksonville Jaguars on Sunday.

The former All-Pro linebacker returned to practice on Wednesday for the first time since Week 1. He had been sidelined due to quad and knee injuries — the nature of which were never revealed.

If Levy indeed misses Sunday’s game, it will be for the 22nd time in the last 24 contests. He missed all but one game in 2015 due to a hip injury.

In 2014, his last full season, Levy finished first on the Lions and second in the NFL with 151 tackles. When healthy, he’s one of the best sideline-to-sideline defenders in the league.

The Lions have certainly missed him at the linebacker position this season, where they’ve looked vulnerable from the get-go.

Levy made headlines earlier this week when he told Men’s Journal that he’s experienced symptoms of the brain disease chronic traumatic encephalopathy (CTE). Earlier on Friday, Caldwell addressed the team’s responsibility to injured players.

Also listed on the Lions’ injury report on Friday were Theo Riddick (ankle) and Ezekiel Ansah (ankle), both of whom were classified as questionable for Sunday’s game.
