Republic of Ireland coach Martin O'Neill is expected to confirm this morning that Rice wants more time to consider his international future as England hover.
Rice's Irish U-21 team-mate Curtis told the LOI Weekly podcast: "He's a young lad and hopefully he makes the right decision and goes with his heart.
"He's a great player and hopefully he does come back to us," continued the in-form Portsmouth attacker who is anxious for another call from O'Neill after being brought in for last month's senior friendly in Poland.
"Declan is a young bloke playing in the Premier League week in and week out for West Ham and he's having a bit of trouble now because his head is all over the place. Hopefully he knows what he wants to do and comes back to us."
