Chris Martin will undergo a medical at Reading on Transfer Deadline Day, Sky Sports News understands.
The Scotland international striker is set to join the fellow Championship club on loan from Derby for the rest of the season.
Martin was considering a loan move to Sunderland after the clubs agreed a deal a fortnight ago, but he appears set to join the Royals.
The 29-year-old striker was with the rest of the Derby squad for some warm-weather training in the Middle East last week, where he was considering Sunderland after the clubs had agreed a loan.
Martin has fallen down the pecking order at Pride Park following the £1.5m signing of Cameron Jerome from Norwich on Wednesday.
Martin was sent on loan to Fulham last season by former manager Nigel Pearson, but wanted to return after he was sacked and Steve McClaren returned at the helm.
