Luke Garbutt will make a timely return to Cheltenham's starting line-up as they set their sights on a win to earn promotion from League Two.
The on-loan Everton left-back missed both legs of the Robins' semi-final meetings with Torquay due to a muscle strain, but has declared himself fit for Sunday's promotion decider.
He said: "I've been out for two weeks and I was back in training (on Monday).
"It was my first training session and I'm back fit for the play-off final now."
Keith Lowe deputised for Garbutt for both games against the Gulls, Mark Yates' men triumphing 4-1 on aggregate, but the 26-year-old may have to be content with a place on the bench at the national stadium.
With Garbutt back in action, Yates has a full squad at his disposal as he muses over which combination of 11 men will best match the Railwaymen to seal a return to League One after a three-year absence.
Meanwhile, Crewe expect to have captain David Artell and midfielder Luke Murphy available for this League Two promotion decider.
Artell was a surprise inclusion at centre-back for the second-leg of the semi-final triumph over Southend, having suffered a broken metatarsal in training ahead of the first game at Gresty Road.
The 31-year-old received encouraging news when an x-ray after the game showed the bone had not moved and he will be able to lead his side out at Wembley if that prognosis remains unchanged.
Murphy missed the 2-2 draw at Roots Hall after suffering a grade two tear to his groin in the decisive first-leg victory.
If he is passed fit, Murphy must oust Lee Bell from central midfield after the former Macclesfield man impressed against the Shrimpers.
Should Crewe manage to secure promotion after three years in the fourth tier they will have extended a club-record unbeaten run to 19 matches.
