Bournemouth manager Eddie Howe does not expect Dominic Solanke to be fit until next month, a day after signing the striker from Liverpool.
Solanke, 21, joined the Cherries on Friday in a deal worth £19 million plus add-ons, a source told ESPN FC.
"Dominic will miss most of January I would say, because he's got a bit of a hamstring issue," Howe said after Saturday's 3-1 defeat to Brighton in the FA Cup.
"It will be more February before we're likely to see him in action, but we knew about that because he's been through all the medicals and checks."
"He adds a slightly different dynamic to our front line: he can hold the ball up in play, he's technically gifted, has a good physical presence and all-round he's a very good player."
Crystal Palace were interested in a loan move for Solanke until their manager Roy Hodgson said on Wednesday that any potential deal was off due to "complications."
Solanke has been sidelined with a muscle issue of late, but a source said the injury is not thought to be serious. The one-cap England international had not featured at all for Liverpool this season.
