Helu remains plagued by tendinitis in his left Achilles tendon.

Helu, who is competing with Evan Royster and Tim Hightower for the starting running back duties, missed Monday’s practice and expected to meet with the Redskins’ trainers for additional treatment before Tuesday’s session.

Helu likely would have started against Chicago after Royster started last week in Buffalo. But he may be forced to watch instead.

“I wish circumstances were better,” Helu said. “But I also know that this is just the hand that I’m dealt and I’ve got to do the best at getting fully healthy before getting out there, because I don’t want things to carry over into the next week, and then we end up bringing things that are hindrances into the season.”

Helu missed time last season with knee and foot injuries, and was sidelined for a portion of the team’s offseason practices by groin and hamstring strains.

He said that he also suffered some Achilles tendinitis last season.

“It’s kind of out of nowhere. It’s just been [getting worse] throughout the weeks. I’ve had it in the past, but not to where it is now,” Helu said.

Redskins coach Mike Shanahan said that Helu may need to do a better job of stretching before practice, and Helu agreed.

“When I pulled my hamstring this spring, that’s something that I saw I need to do a lot more of,” Helu said. “It’s something that I do a lot more of after practice, but I need to do more of before.”

Helu started five games last season and played in a total of 15. He rushed for 640 yards (averaging 4.2 yards per carry) with two touchdowns. He also had 49 catches for 379 yards (7.7 yards per catch) and one touchdown.
