Steven Finn will fly out to South Africa to join up with England`s squad ahead of the opening Test on Boxing Day.
The Middlesex seamer was forced to miss the series against Pakistan in the United Arab Emirates after sustaining a stress-related injury to his foot.
Finn impressed in England`s Ashes win over Australia in the summer, but now faces plenty of competition for a place alongside James Anderson and Stuart Broad.
He was left out of the squad for South Africa to continue his rehabilitation but made a superb return to action last Friday when he took 3-22 in four overs in a Twenty20 game for England Lions against Pakistan A.
Finn then returned figures of 1-30 in Sunday`s win in Dubai and has clearly done enough to prove his fitness to selector Mick Newell, who has been monitoring the Lions in their five-game series which finishes on Wednesday.
Finn said: "I`ve been really pleased with the way things have gone with the Lions. I`ve bowled my overs and my foot has come through fine. I`m excited by the prospect of linking up with the team out in South Africa."
In addition to likely starters Broad and Anderson, England have left-armer Mark Footitt and all-rounders Chris Jordan, Chris Woakes and Ben Stokes competing for places in their attack.
Finn will fly out on Monday night but will not be considered for England`s warm-up clash against a South Africa Invitational XI on Tuesday, the first match of the tour.
Wicketkeeper Jonny Bairstow welcomed the news about Finn and said: "We were really disappointed with Finny getting injured in the UAE, he`s an integral part of our squad and to have him back and hopefully pushing for a place in the first or second Test is fantastic.
"He`s had a bit of a break and he`s raring to go after putting some performances in for the Lions out in Dubai. Finny, with his height and extra bounce and pace will bring a different aspect to our pace attack."
Speaking during Sir Ian Botham`s charity walk in South Africa, former Proteas seamer Shaun Pollock said: "It is a big boost for England to have Finn back.
"You need depth in a squad and I have been impressed with what I`ve seen of him since his change of action. These South African conditions should suit him - he`s a tall man and there is lots of bounce on offer."
Sir Ian Botham says the news that Steven Finn will fly out to South Africa to join up with England`s squad ahead of the opening Test is terrific
