FLORHAM PARK, N.J. - The days have turned to weeks, and now it's unclear exactly when Jace Amaro will see the field again.

The second-year tight end suffered a sprained shoulder in the Jets' preseason opener in Detroit on Aug. 13. And Todd Bowles doesn't seem optimistic about his return. "He won't be practicing no time soon," the Jets coach said Monday.

Amaro, a 2014 second-round pick, was spotted on the field for the first time since the injury. But he spent much of practice in the rehab area with other injured teammates.

Pressed for more details about the extent of Amaro's shoulder injury, Bowles said: "He can't use it. What you want me to say?"

He also said he's not sure if the tight end, who caught 38 passes for 345 yards and two touchdowns last season, will be back for the Jets opener against the Browns. "It all depends on how he's feeling," Bowles said. "I'm not a doctor and if a man can't use his shoulder, I just know he can't play."

Two days after Amaro suffered the injury, the coach estimated it would be a "week-to-week" thing. On Monday, he said trainers told him Amaro would be out "a couple weeks."

Amaro, however, is optimistic. "Hopefully, I'll be ready to go for the Philly game," he told Newsday, referring to the final preseason game against the Eagles at MetLife Stadium. "That's the goal . . . Right now, if I could play through it, I would, but I just can't do it."

LaCosse added to roster

The Jets added their seventh tight end to the roster, Matt LaCosse. The Illinois product had signed with the Giants in May, but was cut Aug. 1. The 6-5, 260-pound LaCosse injured his hamstring during the Giants' first training camp practice. In a corresponding move, the Jets waived injured defensive lineman Davon Walls.
