Coventry saw their promotion confirmed with Friday's draw at Blackburn Rovers.
And with that achievement, a permanent option in Brentford loanee Frank Onyeka's loan deal was reportedly triggered.
The Nigerian international joined Coventry in January on loan until the end of the season, with a permanent option included should the Sky Blues be promoted.
Onyeka has made 12 appearances for Coventry - starting on 11 occasions - with his one goal coming in the 3-2 win over Derby earlier this month.
