Chris Johnson, the first-round draft pick from Texas A&M, is recovering from a knee injury that kept him out of the Cowboys’ preseason opener.
The team confirmed on Thursday that Johnson had a procedure done Thursday and is back to playing.
Johnson missed most of training camp with the injury, but the Cowboys didn’t see him practicing as a rookie until the team announced he had the surgery.
Johnson is expected to miss three to six weeks, but he could be back in time for the Cowboys preseason opener against the Green Bay Packers on Sept. 7.
Johnson was a standout on the team last season with 12 sacks and 29 tackles for loss.
He’s the No. 2 overall pick in this year’s draft, but it’s unclear if he will be able to earn a roster spot in 2017.
The Cowboys signed free-agent linebacker Dontari Poe to replace him.
Poe was a starter on the Cowboys in 2016 but never played in a regular-season game.
Dallas coach Jason Garrett said Johnson’s surgery was the culmination of his rehab.
Johnson, 29, was drafted in the first round by the Cowboys with the 28th overall pick.
