New Steelers tight end Ladarius Green remains on the physically unable to perform list, and Steelers coach Mike Tomlin won’t say how close Green is to returning.

Per Ed Bouchette of the Pittsbugh Post-Gazette, Steelers quarterback Ben Roethlisberger shrugged his shoulders when he was asked about Green’s status and is clearly concerned with the state of the tight end position.

“I don’t want to jump to any conclusions yet because I see flashes from all of them at times with really great stuff,” Roethlisberger said of the Steelers tight ends who have been practicing. “And then you see some stuff that is just [like], man, come on there’s got to be more.”

Heath Miller’s retirement led to the Steelers signing Green away from the Chargers in March. He had ankle surgery last January and is yet to practice with his new team.

That leaves second-year player Jesse James and David Johnson, a fullback/tight end combo who’s back with the Steelers after two seasons with the Chargers, as the team’s top tight ends for now. Otherwise the Steelers have gone through camp with a collection of former practice squad players and undrafted rookies.

Johnson has 24 career catches, six in the last three seasons. James, who’s just 22, caught eight passes as a rookie.

The Steelers still have time — many of their regulars aren’t playing in the team’s preseason opener, anyway — and still have weapons. But the Steelers figure they’re going to throw a lot and score a lot, and they signed Green thinking he’d be a part of that.

“We have options,” Roethlisberger said. “We’ll wait to make any crazy decisions on [schemes] until we get a little further on, and each week may dictate some different groupings, some different schemes, things like that.”

Green, 26, has played in 47 career games and has 77 career receptions. He caught a career-best four touchdown passes last season.
