Shakib Al Hasan is "still being assessed" for a groin injury, which kept him off the field on the third morning of Bangladesh's first Test against West Indies at Zahur Ahmed Chowdhury Stadium, a Bangladesh team spokesman told ESPNcricinfo.

It was unclear whether this was the recurrence of the groin niggle he suffered during the third ODI - in this Test, he appeared in pain when trying to stop a ball with his foot off his own bowling in his third over on the second afternoon.

He went on to bowl a few more overs but after completing his sixth, Shakib slowly walked off the field when Shadman Islam's foot injury gave everyone a break.

This is Shakib's comeback Test match after his one-year ban by the ICC ended on October 29 last year. He made a successful return in the ODIs, winning the Player of the Series award, but it was somewhat marred by the groin niggle he picked during the third ODI.

Shakib had said after the game that "it [the injury] isn't looking good" but later recovered and joined training less than a week later to prepare for the first Test in Chattogram.

Meanwhile, Shadman returned to the field after being hit on the foot during the second day's play.
