DeSean Jackson‘s return to Philadelphia in Week 3 could be in jeopardy because the wide receiver sprained the AC joint in his left shoulder as the Redskins beat the Jaguars, 41-10, on Sunday.

Jackson, who signed with Washington as a free agent this past spring, suffered the injury with just less than seven minutes left in the first quarter. He made a diving attempt at a catch and landed on his shoulder. Shortly after, Jackson retreated to the locker room, flanked by trainers.

Coach Jay Gruden said after the game that tests showed a sprain, and that Jackson will be listed as day-to-day.

Jackson said he would like to play next Sunday at Philadelphia, where he spent the first six seasons of his career. But at the same time, he said he didn’t yet have a feel for how things would play out in the coming week.

“I mean, it’s still early, but you know, I say day-to-day,” he said after the game. “Where I feel now, the pain has eased up a little bit. I look forward to coming back next week and playing. It’s always frustrating not to finish the game out and go out there and battle with my teammates. But we still got the win, so I feel good about that.”

Meanwhile, teammates Darrel Young, Roy Helu Jr. and Shawn Lauvao all had optimism that the injuries they suffered Sunday were less severe.

Young sprained his back when he took a hit at the end of a seven-yard reception. The hit, delivered by safety Winston Guy, left Young stretched out on the field for a couple of minutes. Officials called Guy for unnecessary roughness and a hit to the head, but Young said it was actually a hit to his back and that he didn’t believe that the hit was illegal.

Gruden said he believes Young will be listed as day-to-day.

Helu strained his left knee early in the game and played with the injury until it became too sore for him to continue in the fourth quarter. The running back remained hopeful that he could return to action later this week.

Gruden said that Lauvao had some inflammation in his right knee after what was described by the team as a sprain late in the game. Third-year pro Josh LeRibeus took over for Lauvao at left guard and finished the game. But Lauvao said after the game that he didn’t believe the injury was serious.
