ST. PETERSBURG, Russia -- From his thigh to his foot to the back of the net, Lionel Messi finally scored a goal at this year's World Cup. The exquisite strike from the Argentina great sparked the first of several celebrations from an animated Diego Maradona, who screamed, shouted and made obscene gestures -- and raised concerns for his health.

Argentina staved off elimination with a 2-1 victory over Nigeria on Tuesday, getting a late goal from Marcos Rojo. Maradona showed both middle fingers to the crowd after the 86th-minute winner.

A short time later, videos posted on social media showed Maradona needing help out of the stands and into an adjoining luxury box at the stadium. He appeared to have his eyes closed and a later photo showed a pair of paramedics attending to him.

There was no immediate information on his health, but about two hours later he was photographed smiling at an airport. Another photo posted on Twitter appeared to show him sitting on a plane.

Messi's goal -- his 65th for Argentina -- was surely enough to impress even Maradona.

From a long pass over the defense by Ever Banega, Messi caressed the ball with his left thigh, took another touch with his left foot, and then delivered a smooth right-footed finish into the corner.

Messi fell to his knees and pointed his fingers upward in celebration. At the same time, Maradona crossed his arms with his hands on his shoulders and looked to the sky.

"I knew that God is with us," Messi said, "and he wouldn't let us get eliminated."

Messi, who later hit the post off a free kick, and Banega controlled the game in the first half. Rojo finished it off in the second by cushioning a volley with his right foot into the bottom corner and ensuring Messi's quest for a first World Cup title continued.

Argentina will play France in the last 16 in Kazan on Saturday. If Argentines win and Portugal beats Uruguay on Saturday, Messi would face Cristiano Ronaldo in the quarterfinals.
