RHP Mike Mussina, who sustained a broken nose and cut face when struck in the face by a Sandy Alomar line drive Thursday night, has a mild concussion and likely will miss his next turn in the rotation.
Mussina will not be placed on the disabled list and should be ready to play within 10 days.
"Knowing Mike, he'll probably want to play catch tomorrow," Orioles manager Ray Miller said before Friday night's game against the Devil Rays. "But we're not going DL him."
The Orioles recalled RHP Bobby Munoz, 2-0 with four saves and a 1.59 ERA in 13 games at Triple-A Rochester. C Charlie Greene was optioned to Rochester.
Mussina's next scheduled start was Tuesday at New York. If the Orioles stick to their rotation, Mussina's turn would come up again May 24 at Oakland.
ANGELS: 2B Randy Velarde left Thursday night's game in the sixth because of severe pain in his right elbow, which was surgically reconstructed in 1997. An MRI appeared to show no damage to the reconstructed ligament but some damage to the flexor muscles and bone. He will rest his arm this weekend, take medication and be reevaluated Monday.
RED SOX: The team put rookie RHP Brian Rose on the disabled list and said LHP Steve Avery would take his turn in the rotation today. Rose has inflammation and calcification in his right elbow and will have the option of cortisone injections or rest.
ROYALS: 3B Dean Palmer was a late scratch against the Red Sox because of back spasms.
MARINERS: X-rays were negative on 1B David Segui, who fouled a ball off his foot Thursday. Segui did not play Friday.
RANGERS: Juan Gonzalez reached 50 RBI in 40 games, the fastest since Joe Carter also did it in 40 games with Toronto in 1994.
YANKEES: RHP Frank Lankford, taken by Los Angeles for $50,000 in December's major-league draft, was returned for $25,000.
