BALTIMORE—Mark Trumbo walked through the Orioles’ clubhouse on Thursday afternoon, a day after he was scratched from Norfolk’s starting lineup.

Trumbo, who had been in the final stage of his 20-day rehabilitation assignment, felt soreness in the right knee that had been surgically repaired last September.

He had the knee examined and was given a Platelet-rich plasma injection. Orioles manager Brandon Hyde said that he would be shut down for seven to 10 days, and remain with the Orioles for now.

“Let his knee rest, heal, and hopefully be on track after that,” Hyde said.

Trumbo tried to play during spring training, but late in March he and the Orioles decided that the knee wasn’t up to playing standards and he was put on the 60-day injured list.

He went on a rehab assignment on May 28, and in eight games at Double-A Bowie and Norfolk, he was 6-for-28 (.214) with a home run and two RBIs.

It has been nine months since Trumbo’s surgery, and the timing for Trumbo’s return was always going to be tricky. The Orioles had hoped to use the 33-year-old who is in the final year of a three-year, $37.5 million contract, as a trade chip, but with July 31 the only deadline this year for deals, a trade might not be realistic.

“That was a serious injury, and after surgery, it requires a lot of time to heal,” Hyde said. “There’s not a real timetable on it. He was progressing well, and is progressing well. He just felt some soreness yesterday, but he was running better. He was playing the field and swinging the bat pretty well.

“… I have to give Mark so much credit. To try and come back from something like this … to come back on the field and play, says a lot about him. He’s a high character guy.

“It’s great seeing him here. I wish he was in uniform, but it’s not the case right now.”

Hyde has spoken with Trumbo, who led the major leagues in home runs with 47 in 2016, his first season with the Orioles. In January 2017, he signed a three-year contract, and hit 23 home runs in 2017. Last season, Trumbo was limited to 90 games because of knee surgery and a quad injury.

“I think he’s frustrated,” Hyde said. “He would love to be here and help us. He likes to play. I think he likes the vibe on the club … He had a little setback. It’s a tough thing to come back from.”

Smith, Stewart updates: Dwight Smith Jr., who is on the seven-day concussion injury list, took batting practice on Thursday for the first time since he hit the left field wall in Texas on June 6. Smith is eligible to play on Friday.

“He’s checking a lot of the boxes in a positive way of coming back from a concussion,” Hyde said. “Possibly some time this weekend, but still has to pass a few more tests.”

Stewart, who sprained his right ankle while trying to catch a foul pop in Texas on June 5, is eligible to come off the 10-day injured list on Sunday.

“He’s getting a little bit better every day,” Hyde said. “He’s he going to hit the 10-day mark? I’m not really sure. Maybe not. If he goes much past that, he’s going to have to go on a rehab assignment.”
