The team's management initially said that 22-year-old players would undergo a CT scan and be monitored for the next 48 hours.
However, the Pakistan Cricket Board (PCB) later said that the scan had shown that the player had not been damaged.
"Imam-ul-Haq all scans are clear. He joined the team and will remain under the supervision of Tim Physio," PCB tweeted.
On the pitch, bowler speed Shaheen Shah Afridi recorded his career as the best bowling while Fakhar Zaman's opener reached half a century to help Pakistan win a series-leveling victory.
Shaheen & # 39; s 4-38 made New Zealand go down to 209-9 in their 50 overs before Zaman returned to the form with run-a-ball 88 for seventy-five to guide Pakistan to their target for the loss of four wickets at 40.3 overs.
The top-scoring veteran batsman Ross Taylor for New Zealand with a tiring 120-ball 86 did not come out and added 75 for the fifth goal with Henry Nicholls, who made 33 tiring of 63 balls.
With that victory, Pakistan broke a four-year losing streak of 12 one-day international matches against Black Caps, starting with a 2-3 defeat in the UAE in 2014.
New Zealand also beat Pakistan 2-0 (in New Zealand 2015), 2-0 (in New Zealand in 2016), 5-0 (in New Zealand in January this year) and in the first match of the current series by 47 runs in Abu Dhabi on Wednesday.
The win also made an interesting final match in Dubai on Sunday.
"We want to make a comeback and the team is doing well to do that," said Pakistan captain Sarfraz Ahmed.
"We keep them with a low total shree from Shaheen and then Fakhar and Babar fight very well."
New Zealand captain Kane Williamson acknowledged his team did not place a defensible amount.
"A little scattering makes us total," he said. "That's not enough on the surface. We lost."
Zaman, who has 57 poor people running the last six days an international day, punishes Bowlers in New Zealand with 11 borders and has given Pakistan a fast start with the Imam.
Unaffected by the Imam's injury, Zaman added 101 quickly to the second goal with Babar Azam making the 50-ball 46 before the two fell on the same Ferguson.
Ferguson, who finished 3-60, then had another lucky goal Shoaib Malik for ten when a ferocious tug turned from Nicoll's shoulder and was caught in the middle by Ish Sodhi.
Sarfraz fell for 13 but Mohammad Hafeez hit the winning limit to finish with 27 not coming out.
Earlier, the Taylor-Nicholls stand lifted New Zealand after Shaheen once again shook the top spot after 4-46 in the first match.
Shaheen brushed off the opener that damaged Colin Munro in the second half above the second half, trying hard to catch Hafeez.
In the next match, he deflected a direct shot to finish off Kane Williamson (one) at the end of the non-striker.
In his second spell, Shaheen temporarily conjured Tom Latham, while Hafeez bowed George Worker for 28 years to leave New Zealand by fighting at 73-4.
Taylor, who made 80 in the first match, held one full end and together with Nicholls made sure the innings did not finish below 200.
Nicholls was finally thrown to 38 by Hasan Ali who finished with 2-59.
Taylor hit three limits and six for 43 and a half centuries on an international day.
