Shrewsbury Town forward Ryan Bowman was taken to hospital after suffering heart palpitations during their League One match against Ipswich.
Bowman was substituted in the 35th minute of the 2-1 loss, assessed by medical staff, and then sent to a local medical facility for checks.
Shrewsbury boss Steve Cotterill said: “He had heart palpitations.
“The doctor said his heart was beating up at 250 beats a minute or something.
“We are just hoping that we get a bit more of an update [later on].”
The 29-year-old Bowman joined Shrewsbury from Exeter in the summer.
