Kyle Lafferty returned to Northern Ireland to face the Republic of Ireland and Austria after apologizing for the "verdict mistake".
Lafferty, 31, withdrew from the double header of the Nations League against Austria and Bosnia and Herzegovina last month, citing Ahilov injury.
He informed Neil's Chief Officer NI at midnight on the day before the meeting.
Ireland then called for Fifa's five-day rule, which prevented further appearances on the next weekend.
Participating in Rangers attackers in the games may be in doubt as he was excluded from his club's Europa League game against Spartak Moscow on Thursday night with a quad muscle problem.
"I spoke with Kyle's phone and personally in Glasgow. I also talked to Steven Gerrard (Rangers Manager)," O & # 39; Neill said at the announcement of the 28-mane team.
"It's nice to get him back. The injury is just anxiety, so his availability depends on how he's coming through the weekend."
Before last month was far from the juncture, the manager explained that Lafferty was "excluded from two games," adding that he would be eliminated on his return.
The IFA interview saw that Hamilton Academical was shut down in the next Rangers game.
Lafferty has won 20 international goals even though he has not earned his country since World Cup qualifier 4-0 won Azerbaijan at Windsor Park in November 2016.
Northern Ireland has lost none of the 17 international matches in which Lafferty scored.
Northern Ireland faced the Republic of Ireland in a friendly match on November 15 in Dublin before finishing its national league campaign on November 18 with a match against Austria in Belfast.
Republican side Martin O & # 39; Neilla surpassed Northern Ireland in the newest Fifa rank.
