The 29-year-old Argentina international was suspended for the Serie A bottom side's last outing - a 4-2 reverse against Napoli on Wednesday - after he was sent off in the defeat to Juventus on March 23.
But he returns to boost the attack with struggling Catania desperate for a much-needed win after recording five defeats in their past six matches from which they have collected just one point as they hold up the table.
The match comes too early for Nicolas Spolli to return from injury, while fellow defender Alexis Rolin has been named in the squad after he was sidelined for the midweek defeat.
Udinese coach Francesco Guidolin warned it will be a tough match as Catania will be aiming to fight for their Serie A lives with eight matches of the season remaining, as they sit six points from safety.
Guidolin's side are eight points clear of the relegation zone with a game in hand over Monday night's opponents, and he told his club's official website, udinese.it: "Catania still believe in the possibility of salvation and will play with great determination until the end."
Udinese have collected seven points from their past four matches and Guidolin hopes his side can build on their two-match unbeaten run and move up the table.
He added: "It's a great opportunity and we have to try with all our might.
"The group is aware of the importance of this meeting. Tomorrow, if we are good we will focus on other goals, or try to reach the teams that are ahead of us.
"Meanwhile, however, we think the three points are up for grabs tomorrow."
