David Turnbull’s move to Celtic has been thrown into doubt after an issue arose during the midfielder’s medical.

The Hoops had agreed a £3million deal with Motherwell for the 19-year-old last week, with Turnbull reportedly agreeing on a four-year contract with the club.

However, according to The Herald, the move could now be called off due to an unspecified issue with the midfielder’s medical.

Celtic and Motherwell are now said to be in talks with regards to how to move forwards, and the report suggests the transfer could be in “serious jeopardy.”

Neil Lennon will be hoping the issue is resolved in the near future with the first leg of Celtic’s UEFA Champions League first qualifier against FK Sarajevo coming up in just over three weeks.

The Hoops kick off their pre-season preparations on Wednesday against Austrian outfit Pinkafield before clashes against SC Wiener Neustadt and FC St. Gallen.
