Queens Park Rangers, Wolverhampton Wanderers and Birmingham City are all said to also be tracking Peterborough United striker Conor Washington.
Washington sat out of Peterborough training yesterday, with talks ongoing between the two clubs.
Posh are apparently willing to be happy to sell their prized front man for £3 million, with a move to Reading now looking likely.
QPR, Wolves and Birmingham all want a striker in the transfer window, and it remains to be seen whether they will join Reading by bidding for Washington, who has scored 12 goals in his last 13 matches.
The Royals have identified Washington as their first choice replacement for Nick Blackman, who left to join Derby County at the start of the week, and a deal could go through in the coming days.
