Without any information, hard to give an answer. If you can't think of a reason for that player on the market, post in the bug forum with a link.
Maybe he was sold and bought by the same team ?
just checked and not, it has been sold today to another team. I'm gonna send you via pm the player, I'd like to avoid to make free advertising to day traders
