After scoring a vital late goal against Wexford in the semi-final, Sherlock comes into the Dublin attack at right full-forward with Mark Vaughan making way.
On the Laois team, Sheehan is again preferred to Gary Kavanagh on the left flank of attack.
The recall of Sherlock marks the only change on the Dublin team that defeated Wexford by 1-17 to 2-10 in the semi-final.
Left corner-back Stephen O'Shaughnessy, who was substituted because of injury after 33 minutes of the Wexford clash, to be replaced by Peader Andrews, successfully passed a fitness test last night.
Obviously thrilled by his side's hammering of Kildare in their penultimate game of the competition, Mick O'Dwyer has given the green light to the 15 that started that game, with Chris Conroy at right corner-forward and Brian McDonald in the left corner.
Clare will have wing-back Ronan Slattery available for their All-Ireland football qualifier with Sligo at Castlebar on Saturday.
The dynamic wing back, sent off against Cork in the Munster semi-final, has completed his one month's suspension and is certain to be included in the Banner side that will be announced tomorrow night.
Timmy Ryan, who damaged his shoulder on his comeback in the club championship over the weekend, is almost certain to lose out. Conor Whelan is recovering from a broken collarbone, but has been training with the squad for the last two weeks and is being given every chance to prove his fitness.
Meath will be without long-term injury victims Trevor Giles, Brian O'Reilly, and Daithí O'Regan for their qualifier with Cavan in Clones on Sunday.
Galway footballers, fresh from their Connacht final success, have received another big boost with the news that Joe Bergin should be fit for the All-Ireland quarter-final.
At one stage last week, it seemed that Bergin's career might be in jeopardy, when there were fears his knee injury might be a cruciate ligament problem.
The towering midfielder, who can also play wing-forward, missed the semi-final win over Leitrim and then broke down in training last Sunday week.
"It looked very serious for a time," said Galway boss Peter Ford: "There was a fear that it was a cruciate. We knew we would be without him for the Mayo match, but we had to wait to see that he would be alright.
"Joe expects to be back training next week and we will take things from there. But it looks a lot brighter than a week ago," he said.
Bergin was on the subs' bench on Sunday when Galway regained the Connacht title with a 0-10 to 0-8 victory over old rivals Mayo.
His return to the fold will give Ford and his selectors great options as they bid to go one step further in what is turning out to be a successful season for Galway.
Niall Coleman and Barry Cullinane, the midfield pairing for the Galway U-21s when they recently won the All-Ireland, did well in that sector for Galway on Sunday, but the return of Bergin would give Ford more options.
