Oldham Athletic host Millwall tomorrow afternoon (3pm kick off).
Athletic head into the game in full confidence after picking up seven points from a possible nine last week.
Home wins against Coventry City and Charlton Athletic was followed up by last weekend's goalless draw against Swindon Town.
Those results moved Latics out of the relegation places and up to 19th in Sky Bet League One, one point clear of danger.
Millwall also head into the game full of confidence after reaching the quarter final of the FA Cup last weekend.
The Lions knocked out Premier League sides Bournemouth, Watford and Leicester City to set up a last eight clash with Tottenham.
Millwall have not been beaten since losing 3-0 to Scunthorpe United on December 17.
Since then, Neil Harris' men have not been beaten in 17 games in all competitions, including nine wins.
That has propelled them onto the brink of the play off positions and they currently have 51 points from their 32 games this season.
Sheridan will be without central defender Anthony Gerrard as he serves his final game of a two-match suspension tomorrow afternoon.
Josh Law stepped into the right back role after Brian Wilson moved to central defence and the manager could elect to keep the same squad tomorrow.
Charles Dunne and Cameron Dummigan are both close to full fitness after recovering from long term injuries.
Millwall goalkeeper Jordan Archer, striker Steve Morison and midfielder Jed Wallace are not likely to be fit enough to play tomorrow afternoon but Jake Cooper is available after serving his suspension.
Speaking about the game, the manager said: "It will be a tough game because they are going really well. The manager has done unbelievable, what with the cup as well, to get where they are.
"They have beaten three Premier League teams so you've got to give them a lot of credit for that and the manager has done a brilliant job.
"They are coming off the back of last season as well where they were really strong and unlucky in the play offs so I feel he's doing an excellent job there.
"He's got a good team and when you look at them, you know what you're going to get.
"Each player knows what their job is and they have good players in their team that know what each others strengths are and they play to them and they are effective.
"You don't beat three Premier League teams by luck so a lot of credit goes to them.
"Dave Livermore is there as his assistant as well who played under me, and they are both doing a brilliant job, so it's going to be a real tough game.
"I think they will expect a tough game from us as well and hopefully we will give them one.
"We are at home, I don't care who we are playing, I expect us to win the game and that's what we will be trying to do but I do know it's going to be tough."LAST MEETING
