Will Johnson tests hamstring

PITTSBURGH -- Will Johnson (hamstring) was a limited participant in the Steelers' second practice of the week, but the second-year fullback appears to be on the right track as far as playing Sunday in the season opener.

Johnson said he did individual work Wednesday afternoon while also taking part in some 7-on-7 drills.

“The biggest thing is I wanted to get out here and do some change-of-direction things and sprint 100 percent and see how my leg would react and it held up pretty well,” said Johnson, who got hurt in the Steelers' final preseason game last Thursday.

The Steelers have two more practices and a walkthrough before hosting the Titans.

Rookie outside linebacker Jarvis Jones (chest) was listed as a partial participant in practice. But the first-round draft pick said afterward that he feels fine and is good to go for the season opener.

Jones is expected to play extensively as the Steelers will use a three-man rotation at outside linebacker.

Tight end Heath Miller (knee) was a limited participant in practice, though he has been all but ruled out for Sunday.

Running back Le'Veon Bell (foot) was the only Steelers player who didn't practice on Wednesday. Steelers coach Mike Tomlin has said Bell could do some individual drills this week.

Bell has already been ruled out for the season opener.
