Odemwingie drove to Loftus Road on deadline day in the hope of securing a move to QPR, an act described by Baggies boss Steve Clarke as 'total lunacy', with the two Premier League clubs unable to agree terms.
And the 31-year-old, who missed West Brom's 1-0 defeat to Tottenham on Sunday, has been linked with a loan switch to the Eagles, with the view to a possible permanent summer move if the club are promoted.
When asked about the Championship club being linked to Odemwingie, Holloway said: "I haven't got a clue about that. Someone contacted the chairman.
"I was asked would I want him? I said yes.
"I don't really think that's a realistic target for us personally".
Odemwingie launched numerous Twitter outbursts against West Brom after having his transfer request rejected, but Clarke will be aware that the Nigeria international's departure would reduce his options.
Meanwhile, West Brom are set for a second attempt by Blackburn to sign winger Jerome Thomas on loan, after a £600,000 move to Ewood Park last Thursday failed to go through in time.
