This marks Matthews’ third stint at the club in two seasons.
He initially joined Eastleigh in January 2016 – shining during a difficult period for the Spitfires, scoring 3 goals in a dozen appearances.
Since returning to the club in August 2017, he has made a further twenty-one appearances, scoring 2 goals.
Manager Andy Hessenthaler told his club`s official website: “We’re over the moon, obviously. He’s been terrific – we played him in a slightly different role on Saturday, just behind the striker, which I think suits him.
“I’m sure Bournemouth have seen how he’s getting on – it’s great for his development here, and they’re happy for him to stay until the end of the season. He’s a pleasure to work with.”
Matthews said: “I’m obviously really pleased to extend my loan until the end of the season.
“We’ve had a difficult first half of the season, but in the last few games we’ve picked up a few good results and have the momentum with us now.
“Hopefully we can continue the form we’ve shown and keep pushing on”.
