Azam Khan, a hard-hitting Pakistani batter, was taken to the hospital after sustaining a head injury during training in Guyana on Friday. The 22-year-old, who made his debut against England earlier this month, is said to have been hit by a fast bowler and has undergone a CT scan as a precaution.

Following an assessment, a neurosurgeon recommended a 24-hour period of observation. On Monday, he’ll be evaluated again, and a decision on his availability for the fourth and final T20I of the series will be made.

While no official word has been released, Khan is almost certainly out of Saturday’s game in Providence, which is the second of four T20Is between the West Indies and Pakistan. On Wednesday, the two teams competed in a rained-out T20I match in Barbados, with only nine overs available.

Khan hasn’t got the chance to nail down a fiercely fought middle-order spot since being called up to the national team ahead of the T20 World Cup squad announcement. Azam Khan was backed by Coach Misbah ul Haq, who believed it was unreasonable to condemn the 22-year-old on the back of just two knocks against England. Azam scored 5* and 1 in each of the two games he played. He didn’t get a chance to bat in the first T20I against West Indies in Barbados since the match was called off due to rain.

All three remaining games will be played in Guyana, with Saturday’s encounter serving as the first of two back-to-back weekend matches before the final match on Tuesday. The T20Is will be followed by two Tests, which will be played in Kingston on August 12 and 20.
