ST. PETERSBURG, Fla. -- Tampa Bay right-hander Jeff Niemann left with one out in the second inning of Thursday night's 5-4 loss to Baltimore after being hit in the right shoulder by Miguel Tejada's line drive.
The team said Niemann has a bruised shoulder and is day to day.
"Hopefully I should be back out there in five days," Niemann said. "It's pretty sore, it tightened up a lot. It's just muscle. X-rays are fine. There's nothing really wrong."
After being looked at and then throwing several warmup tosses, Niemann was taken out by Rays manager Joe Maddon and replaced by Andy Sonnanstine.
Niemann went 13-6 with a 3.94 ERA in 31 games, including 30 starts, last season. He threw 12 pitches Thursday in his first start this year.
