Manny Machado and the Baltimore Orioles will learn today just how badly the third baseman’s right knee is injured and how long he might be out of the lineup.

The injury to the knee, which is not the one on which he has season-ending surgery last year, looked serious initially, but he was walking without crutches or help in the locker room after the Orioles’ 11-3 victory over the Yankees at Camden Yards. X-rays were negative, but Machado will undergo an MRI today.

“We will know more tomorrow about what’s wrong with it,” Machado said Monday night (via the Baltimore Sun). “The MRI will give us an idea of how many days I’m going to be out. That’s what’s going to tell us what’s going on.”

Machado appeared to sprain his knee as he hit a broken-bat grounder in the third inning. He fell to the ground, grabbing his knee, and was helped off the field by head athletic trainer Richie Bancells and manager Buck Showalter.

“[It’s] just a little sore,’’ Machado said. “A little sore … We’ll just keep icing it, and hopefully it’s nothing too bad. That’s what we are praying for. We’ll just wait and see. It’s just a waiting process. Wait ’til tomorrow morning.”

Machado underwent surgery after hurting his left knee last September and missed the first month of the season while still recovering. His assessment of his right knee injury was encouraging to Showalter.

“He seems to be in pretty good spirits, considering he has had some experience with it, so we’re hoping for good news tomorrow,’’ Showalter said. “There’s a chance that we dodged a bullet. We’ll see.”

Machado is hitting .278 on the season, but, over the last 10 games, is hitting .341.
