Roger Bernadina came away from his injury today without any lingering damage. Manager Davey Johnson plans to play Bernadina tomorrow in the Nationals’ exhibition against the Red Sox at Nationals Park.

After the ball hit Bernadina on the outside of his right knee, he felt a lot of pain and experienced swelling. But after icing his knee, Bernadina – who called his possible opening day assignment “an honor” – felt confident he would be ready for opening day.

“I should be fine,” Bernadina said.

Original post: Shortly after Manager Davey Johnson anointed him the Nationals’ likely opening day center field, Roger Bernadina left this afternoon’s game in the first inning with an apparent leg injury.

Bernadina led off the game and reached on an error. Red Sox starter Aaron Cook tried to pick him off, but his errant throw drilled Bernadina in the leg and rolled away. Bernadina sprinted to second and stood slowly. A trainer tended to him, and he walked off the field. Later, he limped back to the Nationals’ clubhouse.

About an hour before today’s first pitch, Johnson said he is “leaning toward” starting Bernadina in center field with Rick Ankiel on the disabled list.

UPDATE: Bernadina left the game with a right knee contusion and the Nationals consider him day-to-day, a team spokesman said.
