The Detroit Lions held out several players from Wednesday morning's practice session, including rookie safety Louis Delmas, according to mlive's Tom Kowalski.

Delmas had swelling in his knee following Tuesday's afternoon practice. The injury isn't considered serious, and he will be listed as day-to-day.

The same applies to receiver Calvin Johnson (right hand), who told Kowalski "I'm fine, it's not bothering me.

Fellow safety and possible starter Daniel Bullocks (knee), tight ends Brandon Pettigrew (thigh) and Casey FitzSimmons (ankle), DT Grady Jackson, and RB Maurice Morris (leg) also missed practice, according to Kowalski.

The Lions don't anticipate any of the players missing much practice time.
