The Wales international, on loan at the Cherries this season, was not able to face Chelsea on Saturday due to "strange" leg injury.
Asked for an update on the Wrexham-born star's injury, Howe told the Daily Echo: "Harry's is a strange one. He suffered a knock on his leg, a dead leg.
"But it's swelled up and the swelling keeps returning.
"We are going to probably get him back to Liverpool this week and hope he can be back very soon."
He added: "Liverpool will have a look at him early in the week.
"I just think it's the right thing to do with him obviously being contracted to Liverpool, just to check he's okay."
