The Washington Redskins will miss wide receiver DeSean Jackson for about a month after straining his left hamstring in the team’s opening game of the season against the Miami Dolphins.

The Redskins suffered the 17-10 loss to the Dolphins with Jackson hurting his hamstring on the opening play of the team’s second series. Jackson was trying to catch a deep throw from quarterback Kirk Cousins. Adam Schefter of ESPN updated the Jackson injury on Twitter.

“Possibly, it could be shorter, but you just never know with hamstrings," Redskins head coach Jay Gruden said to Fox Sports. "You hate to lose a star, especially with his speed. We feel good about the receivers that take his place, but nobody can substitute him for that burning speed that gets down field and scares safeties and corners to death."

The team will also miss Chris Culliver in the next game because of a suspension and safety Duke Ihenacho for a longer period due to a surgery on a fractured left wrist. The Redskins may go with Andre Robert, Ryan Grant, Evan Spencer or Jamison Crowder in Jackson's absence.

The 28-year-old Jackson is playing in his second year with the Redskins after suiting up for the Philadelphia Eagles from 2008 to 2013. In 15 games for Washington last season, he recorded 1,169 receiving yards on 56 receptions with six touchdowns.
