Running back Roy Helu said the Achilles tendinitis in his left foot is nothing new. He had cases of it as a rookie in 2011.

But there is a difference this time.

“It was nothing to this extreme,” he said.

Hence, Helu isn’t sure when he’ll return. He said he was going to talk to the trainers following an open locker room session with the media and that he wasn’t sure if he’d practice Tuesday afternoon.

He said he’s not sure about whether or not he’ll play Saturday at Chicago.

“I wish circumstances were better, but I know that this is just the hand I’m dealt, and I have to do the best with getting fully healthy before getting out there,” he said, “because I don’t want to carry things over to next week, and then we end up building things up to going into the season, you don’t want to carry certain things, hindrances into the season.”

Helu said he doesn’t see a pattern of leg injuries – he was slowed by a right knee issue last season. He also pulled his hamstring in the spring.

“No, because they’ve been on opposite sides, which I’m also not that well versed in how the muscles work,” he said. “I know … something happens because of something in the hips, but there’s nothing I’ve pinpointed yet.”

Stretching more would help, he said.

“When I pulled my hamstring this spring that was something I saw I needed to do a lot more,” he said, “and that’s something that I’m improving on, and I do after practice a whole lot, but prior to practice I haven’t done much of it. I’m naturally a tight person.”
