The Royals, who remain in the Sky Bet Championship play-off spots despite Saturday's 2-0 defeat by Sheffield Wednesday, were unable to add to their squad in January due to the ongoing uncertainty around the ownership of the club.
Chairman John Madejski has held in discussions with several interested parties looking to take full control of Reading but has yet to strike a deal.
However, the Royals did manage to hold onto their star names such as striker Adam Le Fondre, who was linked with a deadline-day move to Cardiff.
They also have a host of players, including Wayne Bridge, Sean Morrison and Mikele Leigertwood, due to return after spells out injured.
"We have got a number of players coming back from injury and we have a strong squad," said Hammond.
"Unfortunately the ownership issues prevented us from adding to the squad, but more importantly we did not lose anyone and managed to keep the group together."
