The 32-year-old goalkeeper joined the R's from West Ham United in the summer, but has since dropped out of the team following Julio Cesar's arrival at the club.
"Does Rob have a future here? Absolutely. I think Cesar has been exceptional. He acquitted himself really well again in the game against Reading last week. He saved a penalty and he's in my thinking for West Ham, certainly," Hughes told Sky Sports News.
