John Ogu Sprains Left Knee

One - cap Nigeria international John Ugochukwu Ogu has not been selected by Pedro Emmanuel, manager of Académica, in his 18 - man squad for the trip to Gil Vicente , which corresponds to the 25th round of matches in the Portuguese championship.

The 24 - year - old central midfielder misses Sunday's game due to a sprained left knee. 

At the moment, his duration on the sidelines is unknown until further tests.

John Ogu has made 18 appearances for Académica in the Primeira Liga , with his last start coming against Estoril on March 17.

He is one of the 30 players named by coach Stephen Keshi to prosecute the Super Eagles summer fixtures.
