Napoli goalkeeper Alex Merritt will be absent from his team's match today against Lazio in the Italian league stage 19 matches because of the injury caused by the Belgian striker Romelio Lukaku.
Lukaku fired a powerful shot at a goal-scoring shot during his team's Inter Milan match with Napoli last week, which ended with Inter's 3-1 victory.
The grenade, which had an estimated speed of 111 km per hour, caused the guard to hit the wrist, after trying to block the ball that drove his nets.
Inter top the league standings with 45 points, one goal difference from defending champions Juventus.
