"Precautionary," Hudson said, before scurrying off to the training room. "... Feeling good."
Hudson certainly didn't feel good Wednesday, when he left the Padres' 3-0 victory after aggravating the right groin strain that caused him to miss seven games earlier this month.
Hudson felt a tug in the same spot after bouncing into a double play against the Dodgers.
According to the team, Hudson is listed as day to day.
The Padres played two games on Thursday with Minor Leaguer Jonathan Galvez starting at second base in the game against the Rockies in Tucson. Everth Cabrera got the start at the same position against the Indians in Peoria.
Depending on how long Hudson is out of action this time, the Padres figure to give additional looks at the position to Cabrera and Andy Parrino, the two players battling for the backup infielder job.
