Carrico joined the Royals in January but made just three Premier League appearances due to a number of factors.
Hammond told the club's official website: "I feel for him, he came in January and following both his contractual situation and an injury he wasn't up to speed at first. But he's been a great professional, he works hard and he's a good player.
"There is some interest but we'll see how it progresses, there are no done deals.
"It's been tough for him, he's become frustrated with the situation but I want to re-iterate he's a good man, works every day and the level of club interested tells you what a good player he is.
"Is there a done deal? No. Is there likely to be? Possibly."
