Barnsley face Millwall in Sunday's League One play-off final, with a place in the Championship at stake.

The Tykes have no new injury concerns as the Johnstone's Paint Trophy winners prepare for their second visit to Wembley this season.

Millwall will check on Byron Webster (hamstring), with Tony Craig set to start at centre-back if he is unfit.

Lions top scorer Lee Gregory, who has 27 goals this season, is expected to shake off a niggling groin problem.

Barnsley were bottom of League One in December but put together an extraordinary run of form under interim boss Paul Heckingbottom to take the final play-off place.

They defeated Walsall 6-1 on aggregate in their semi-final tie to reach the final.

Millwall are eyeing an immediate return to the Championship, having seen their five-year stay in the second tier end last year.

The Lions finished fourth in the table under Neil Harris, who played when Millwall won the League One play-off final against Swindon in 2010.

Midfielder Jimmy Abdou and striker Steve Morison are among four other members of that side who could feature at Wembley again on Sunday.

Barnsley interim manager Paul Heckingbottom told BSports Radio Sheffield:

"We have a group who are young, they're athletic and fit, so we play with pace and we play to their strengths.

"We try to use their strength, so the minimum is the opposition has to match us, and now the belief that when they apply themselves and make good decisions, they are a force."

Millwall manager Neil Harris told BSports Radio London:

"We are confident but not arrogant. We have a tough opposition and a difficult game but we are in the final on merit.

"Wigan and Burton deserve to go up but in performances and the points gained, we and Barnsley may be the top two sides since the turn of the year.

"Barnsley played at Wembley this year but they didn't play against Millwall or in front of our fans there.

"We have come a long way but to be a success, the season is now defined in one game. We have to perform."
