Joe Launchbury was always confident he would be fit to take his place in England's pack for the RBS Six Nations decider against Wales on Saturday.
The Wasps lock suffered a hyper-extended elbow during the 18-11 win over Italy at Twickenham and looked in danger of missing out on the showdown in Cardiff.
However, after coming through a morning line-out session alongside fellow injury doubt Geoff Parling, the 21-year-old has been selected by national boss Stuart Lancaster in the second row.
"I made a passing tackle and hype-extended my elbow in the movement," Launchbury explained to Sky Sports. "It caused quite a bit of pain and the last 20 minutes of the game were hard work.
"I think it was always going to be a late call, though we were both confident that I'd be alright.
"I've worked hard this week with the medical team and now I feel ready to go.
"When the game finished on Sunday I thought there was a chance I was going to miss it (the game against Wales) and I was gutted.
"I'm really fortunate that I've managed to turn it around and be ready for the weekend."
England go into the match at the Millennium Stadium this weekend knowing a victory over the reigning champions will not only clinch them the Six Nations title but also a Grand Slam.
Owen Farrell is another England player passed fit, the fly-half having recovered from the calf strain that kept him out of the Italy victory.
"Playing in the Six Nations with the chance to go through the tournament without losing a game is what everybody dreams of," said Farrell.
"There is no better place to do it (complete the Grand Slam) than to go down to the Millennium Stadium.
"It (England's recent success) is no surprise to any of the lads that have been involved, once we've seen the things that have been implemented (by the coaching staff) and the hard work that's gone on behind that."
