James Henry was one of four players signed on loan by Norwich over the last two days of the January 2008 transfer window.

An 18 year old winger from Reading, Henry came highly recommended. Glenn Roeder said he was delighted that Reading boss Steve Coppell had agreed to release him. He said: “I like taking players from Steve Coppell because he only has a certain type of player. They must be well motivated. I've done my homework and I am told both boys fit the bill in terms of attitude and desire. Steve has high hopes for Henry."

Wide player Henry, 6ft 1in, is an England Under-18 international. He has had loan spells at Nottingham Forest and Bournemouth, where he scored two goals on his debut for the club in a 2-0 victory at Bristol Rovers, and made his senior Reading debut in the 2007/8 season's Carling Cup, as a substitute in a 4-2 home defeat by Liverpool.

Henry made his debut for Norwich in the home win over Preston on 2nd February 2008.

On 18 March 2008, the deal was terminated by mutual agreement as the Royals felt he wasn’t getting enough of a run out. "I spoke to Nick Hammond and he was concerned James wasn't getting involved as much as he would like him to be and that it was best if he went back," City boss Glenn Roeder told the club's official website. "Although he didn't break into the first team as much as would have been ideal during his time here, he was always a pleasure to work with and he's a very talented player. I'm sure he will go on to be an excellent player for Reading.”

Henry made his Reading league debut in December 2008 against Blackpool. In February 2009, he was loaned out to Millwall for a month. He returned to Millwall on loan in September 2009 until December 2009

James joined Millwall for the third time, this time on a three year deal for an undisclosed fee, on 28th July 2010

On 2nd October 2011, the Football League Paper reported that Henry was a prime target for Ipswich who had had two bids rejected
